Java.io.ioexception Stream Is Not In The Bzip2 Format: A Guide to Troubleshoot and Resolve This Prob



File splitting also benefits block-based compression formats such as bzip2. You can read each compression block on a file split boundary and process them independently. Unsplittable compression formats such as gzip do not benefit from file splitting. To horizontally scale jobs that read unsplittable files or compression formats, prepare the input datasets with multiple medium-sized files.




Java.io.ioexception Stream Is Not In The Bzip2 Format




The benefit of output partitioning is two-fold. First, it improves execution time for end-user queries. Second, having an appropriate partitioning scheme helps avoid costly Spark shuffle operations in downstream AWS Glue ETL jobs when combining multiple jobs into a data pipeline. For more information, see Working with partitioned data in AWS Glue.


The enum represents 2 available read modes: splittable and not, exactly as it was explained in the previous section for Bzip2 compression format. The method creating input stream works only for seekable data (= seekableIn must implement Seekable interface). Thus we can freely move inside such compressed file. The method uses start and end parameters to find the position marking the beginning and the end of the read.


The default rollover strategy accepts both a date/time pattern and an integer from the filePattern attribute specified on the RollingFileAppender itself. If the date/time pattern is present it will be replaced with the current date and time values. If the pattern contains an integer it will be incremented on each rollover. If the pattern contains both a date/time and integer in the pattern the integer will be incremented until the result of the date/time pattern changes. If the file pattern ends with ".gz", ".zip", ".bz2", ".deflate", ".pack200", or ".xz" the resulting archive will be compressed using the compression scheme that matches the suffix. The formats bzip2, Deflate, Pack200 and XZ require Apache Commons Compress. In addition, XZ requires XZ for Java. The pattern may also contain lookup references that can be resolved at runtime such as is shown in the example below.


The SocketAppender is an OutputStreamAppender that writes its output to a remote destination specified by a host and port. The data can be sent over either TCP or UDP and can be sent in any format. You can optionally secure communication with SSL. Note that the TCP and SSL variants write to the socket as a stream and do not expect response from the target destination. Due to limitations in the TCP protocol that means that when the target server closes its connection some log events may continue to appear to succeed until a closed connection exception is raised, causing those events to be lost. If guaranteed delivery is required a protocol that requires acknowledgements must be used.


The core of the XZ Utils compression code is based onLZMA SDK, but it has been modifiedquite a lot to be suitable for XZ Utils. The primary compressionalgorithm is currently LZMA2, which is used inside the .xz container format.With typical files, XZ Utils create 30 % smaller output than gzip and15 % smaller output than bzip2.


The accel-config package is now available on Intel EM64T and AMD64 architectures as a Technology Preview. This package helps in controlling and configuring data-streaming accelerator (DSA) sub-system in the Linux Kernel. Also, it configures devices through sysfs (pseudo-filesystem), saves and loads the configuration in the json format.


Red Hat provides CVE OVAL feeds in the bzip2-compressed format, and they are no longer available in the XML file format. The location of feeds for RHEL 8 has been updated accordingly to reflect this change. Because referencing compressed content is not standardized, third-party SCAP scanners can have problems with scanning rules that use the feed.


DEFLATE is the most common compression algorithmused in the zip format, but it is only one of many options.Probably the second most common algorithm is bzip2,while not as compatible as DEFLATE,is probably the second most commonly supported compression algorithm.Empirically, bzip2 has a maximum compression ratio of about 1.4 million,which allows for denser packing of the kernel.Ignoring the loss of compatibility,does bzip2 enable a more efficient zip bomb?


So far we have used a feature ofDEFLATE to quote local file headers,and we have just seen that the same trickdoes not work with bzip2.There is an alternative means of quoting,somewhat more limited,that only uses features of the zip formatand does not depend on the compression algorithm.


Logging the raw stream of data flowing through the ingest pipeline is not desired behavior inmany production environments because this may result in leaking sensitive data or security relatedconfigurations, such as secret keys, to Flume log files.By default, Flume will not log such information. On the other hand, if the data pipeline is broken,Flume will attempt to provide clues for debugging the problem.

Requires the consumer andaccess tokens and secrets of a Twitter developer account.Required properties are in bold.


  • So there are four things useful to know about this release:It's not a simple drop in like previous releases, if you wish migrate to it you will need to recompile your application.

  • If you avoid deprecated methods it should be relatively painless to move to version 2.0

  • The X509Name class will utlimately be replacde with the X500Name class, the getInstance() methods on both these classes allow conversion from one type to another.

  • The org.bouncycastle.cms.RecipientId class now has a collection of subclasses to allow for more specific recipient matching. If you are creating your own recipient ids you should use the constructors for the subclasses rather than relying on the set methods inherited from X509CertSelector. The dependencies on X509CertSelector and CertStore will be removed from the version 2 CMS API.

Base support for CMS (RFC 2630) is now provided (see CONTRIBUTORS file for details).2.65.1 VersionRelease: 1.11Date: 2001, December 102.65.2 Defects FixedX9.23 padding of MACs now works correctly with block size aligned data.Loading a corrupted "UBER" key store would occasionally cause theappearance of hanging. This has been fixed.Loading a PKCS12 store where not all certificates had PKCS9 attributesassigned to them would cause a NullPointerException. This has been fixed.The PKCS12 store wasn't correctly recovering certificate chains oflength less than 2 on calling the getCertificateChain method. This has beenfixed.Lone certificates were not been stored in the PKCS12 store. This has been fixed.CFB and OFB modes weren't padding iv's more than 1 byte less than the block size of the cipher if the mode was reused with a shorter IV. This hasbeen fixed.IV handling and block size return values for CFB and OFB modes wasn't being handled in the same way as the Sun reference implementation. This has been fixed.CertificateInfoRequests were not handling null attributes correctly. Thishas been fixed.Tags for the X.509 GeneralName structure were wrongly encoded. This has beenfixed.getExtensionValue for X.509 certificates was returning the value of theDER-Encoded octet string not the DER-Encoded octet string as required. This hasbeen fixed.reset on the version 3 X.509 certificate generator was not flushing theextensions. This has been fixed.The NetscapeCert type bits were reversed! This has been fixed.2.65.3 Additional Functionality and FeaturesThe lightweight API and the JCE provider now support ElGamal.X509Principal, and X509Name now supports the "DC" attribute and thecreation of directory names from vectors.RSA-PSS signature padding has been added to the lightweight API.EC Public/Private keys are now encoded in accordance with SEC 1. The librarywill still read older keys as well.Added PKCS12-DEF a pkcs12 based key store which works around a bug inthe Sun keytool - it always uses the default provider for creating certificates.A cut down version of the Rijndael has been added that provides the functionality required to conform the the AES. It is designed to fully support FIPS-197. A fips AES wrapper (AESWrap in the JCE, AESWrapEngine in the lightweight library has also been added).Elliptic curve routines now handle uncompressed points as well as thecompressed ones.2.65.4 Other changesAs the range of public key types supported has expanded the getPublicKeymethod on the SubjectPublicKeyInfo class is not always going to work. Themore generic method getPublicKeyData has been added and getPublicKey nowthrows an IOException if there is a problem.2.66.1 VersionRelease: 1.10Date: 2001, October 202.66.2 Defects FixedThe PKCS12 Key Store now interoperates with the JDK key tool. Note: this does mean the the key name passed to the setKeyEntry calls has becomesignificant.The "int" constructor for DERInteger only supported ints up to 128. Thishas been fixed.The ASN.1 input streams now handle zero-tagged zero length objects correctly.2.66.3 Additional Functionality and FeaturesThe JCE Provider and the lightweight API now support Serpent, CAST5, and CAST6.The JCE provider and the lightweight API now has an implementation of ECIES.Note: this is based on a draft, don't use it for anything that needs tobe kept long term as it may be adjusted.Further work has been done on performance - mainly in the symmetric ciphers.Support for the generation of PKCS10 certification requests has been added.2.67.1 VersionRelease: 1.09Date: 2001, October 62.67.2 Defects Fixedfailure to pass in an RC5 parameters object now results in an exceptionat the upper level of the JCE, rather than falling over in the lightweightlibrary.ISO10126Padding now incorporates the correct amount of random data.The PKCS12 key store wasn't picking up certificate chains properlywhen being used to write PKCS12 files. This has been fixed.The Twofish engine would call System.exit if the key was too large.This has been fixed.In some cases the ASN.1 library wouldn't handle implicit tagging properly.This has been fixed.2.67.3 Additional Functionality and FeaturesSupport for RC5-64 has been added to the JCE.ISO9796-2 signatures have been added to the JCE and lightweight API.A more general paddings packge for use with MACs and block ciphers had been aded to the lightweight API. MACs now allow you to specify padding.X9.23 Padding has been added to the JCE and lightwieght API. The oldPaddedBlockCipher class is now deprecated see org.bouncycastle.crypto.paddings for details.SHA-256, SHA-384, and SHA-512 are now added. Note: while the public reviewperiod has finished, these algorithms have not yet been standardised, in theevent that final standardisation changes the algorithms these implementationswill be changed.It's now possible to set bag attributes on items to go into a PKCS12 store,using the org.bouncycastle.jce.interfaces.PKCS12BagAttributeCarrier interface.More classses have been added to the ASN.1 package for dealing withcertificate extensions and CRLs including a CRL generator. Note: theCRL generators should be regarded as under development and subject to change.There's now an examples package for the JCE (in addition to the examplesin org.bouncycastle.jce.provider.test) - org.bouncycastle.jce.examples. Itcurrently consists of a class showing how to generate a PKCS12 file.The X.509 CertificateFactory now includes CRL support. DER or PEM CRLs may be processed.The BigInteger library has been written with a view to making it lessresource hungry and faster - whether it's fast enough remains to be seen!2.68.1 VersionRelease: 1.08Date: 2001, September 92.68.2 Defects FixedIt wasn't possible to specify an ordering for distinguished names inX509 certificates. This is now supported.In some circumstances stream Ciphers in the JCE would cause null pointerexceptions on doFinal. This has been fixed.Unpadded ciphers would sometimes buffer the last block of input, evenif it could be processed. This has been fixed.The netscape certificate request class wouldn't compile under JDK 1.1. Thishas been fixed.2.68.3 Additional Functionality and FeaturesISO 9796-1 padding is now supported with RSA in the lightweightAPI and the JCE.support classes have been added for reading and writing PKCS 12 files,including a keystore for the JCA.The message digests MD4, Tiger, and RIPEMD128 have been added to theJCE and the lightweight API. Note: MD4 and RIPEMD128 have been added forcompatibility purposes only - we recommend you don't use them for anything new!The JDK 1.1 certificate classes didn't conform to the JDK 1.2 API asthe collections class was not present. Thanks to a donated collections APIthis is fixed.2.69.1 VersionRelease: 1.07Date: 2001, July 92.69.2 Defects FixedIt turned out that the setOddParity method in the DESParameter classwas indeed doing something odd but not what was intended. This is nowfixed. Note:This will affect some PBE encryptions that were carriedout with DES, equivalent PBE ciphers to the old PBE DES cipher can beaccessed by prepending the work "Broken" in front of the original PBE ciphercall. If you want an example of how to deal with this as a migration issuehave a look in org.bouncycastle.jce.provider.JDKKeyStore lines 201-291.2.70.1 VersionRelease: 1.06Date: 2001, July 22.70.2 Defects FixedDiffie-Hellman keys are now properly serialisable as well asencodable.Three of the semi-weak keys in the DESParameters, and the DESKeySpec lookup table, were incorrect. This has been fixed.DESEDE key generators now accept 112 and 168 as the key sizes, as wellas 128 and 192 (for those people who don't like to count the parity bits).Providing no strength parameter is passed to the DESede key generator inthe JCE provider, the provider now generates DESede keys in the k1-k2-k1format (which is compatible with the Sun reference implementation), otherwiseyou get what you ask for (3-DES or 2-DES in the minimum number of bytes).Base Diffie-Hellman key agreement now works correctly for more than twoparties.Cipher.getAlgorithmParameters was returing null in cases where a cipherobject had generated it's own IV. This has been fixed.An error in the key store occasionally caused checks of entry types toresult in a null pointer exception. This has been fixed.RSA key generator in JCE now recognises RSAKeyGenerationParameterSpec.Resetting and resusing HMacs in the lightweight and heavyweight librariescaused a NullPointer exception. This has been fixed.2.70.3 Additional FunctionalityISO10126Padding is now recognised explicitly for block ciphersas well.The Blowfish implementation is now somewhat faster.2.70.1 VersionRelease: 1.05Date: 2001, April 172.70.2 Defects FixedThe DESEDE key generator can now be used to generate 2-Key-DESEDEkeys as well as 3-Key-DESEDE keys.One of the weak keys in the DESParameters, and the DESKeySpec lookup table, was incorrect. This has been fixed.The PKCS12 generator was only generating the first 128-160 bits of thekey correctly (depending on the digest used). This has been fixed.The ASN.1 library was skipping explicitly tagged objects of zero length.This has been fixed.2.70.3 Additional FunctionalityThere is now an org.bouncycastle.jce.netscape package which hasa class in for dealing with Netscape Certificate Request objects.2.70.4 Additional NotesConcerning the PKCS12 fix: in a few cases this may cause some backwardcompatibility issues - if this happens to you, drop us a line atfeedback-crypto@bouncycastle.organd we will help you get it sorted out. 2ff7e9595c
