Takeshi Yamamuro updated SPARK-21276: ------------------------------------- Affects Version/s: 2.2.0 > Update lz4-java to remove custom LZ4BlockInputStream > ----------------------------------------------------- > > Key: SPARK-21276 > URL: https://issues.apache.org/jira/browse/SPARK-21276 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 2.1.1, 2.2.0 > Reporter: Takeshi Yamamuro > Priority: Trivial > > We currently use custom LZ4BlockInputStream to read concatenated byte stream > in shuffle > (https://github.com/apache/spark/blob/master/core/src/main/java/org/apache/spark/io/LZ4BlockInputStream.java#L38). > In the recent pr (https://github.com/lz4/lz4-java/pull/105), this > functionality is implemented even in lz4-java upstream. So, we might update > the lz4-java package that will be released in near future. > Issue about the next lz4-java release > https://github.com/lz4/lz4-java/issues/98 > Diff between the latest release and the master in lz4-java > https://github.com/lz4/lz4-java/compare/62f7547abb0819d1ca1e669645ee1a9d26cd60b0...6480bd9e06f92471bf400c16d4d5f3fd2afa3b3d > * fixed NPE in XXHashFactory similarly > * Don't place resources in default package to support shading > * Fixes ByteBuffer methods failing to apply arrayOffset() for array-backed > * Try to load lz4-java from java.library.path, then fallback to bundled > * Add ppc64le binary > * Add s390x JNI binding > * Add basic LZ4 Frame v1.5.0 support > * enable aarch64 support for lz4-java > * Allow unsafeInstance() for ppc64le archiecture > * Add unsafeInstance support for AArch64 > * Support 64-bit JNI build on Solaris > * Avoid over-allocating a buffer > * Allow EndMark to be incompressible for LZ4FrameInputStream. > * Concat byte stream -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
