----------------------------------------
Summary: 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
Reporter: Takeshi Yamamuro
Priority: Trivial
We currently use custom LZ4BlockInputStream to read concatenated byte stream
(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

- Diff between the latest release and the master in lz4-java

* 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
