Resolution: Duplicate
> Remove lz4 hadoop wrapper classes after Hadoop 3.3.2
> ----------------------------------------------------
>
> Key: SPARK-36679
> URL: https://issues.apache.org/jira/browse/SPARK-36679
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.3.0
> Reporter: L. C. Hsieh
> Priority: Major
> Fix For: 3.3.0
>
>
> Lz4-java as provided dependency is not correctly excluded from relocation in
> Hadoop shaded client libraries in Hadoop 3.3.1. (HADOOP-17891)
>
> In order to deal the issue without reverting back to non-shade client
> libraries, we add a few Lz4 Hadoop wrapper classes `LZ4Factory`,
> `LZ4Compressor`, and `LZ4SafeDecompressor`, under the package
> `org.apache.hadoop.shaded.net.jpountz.lz4`.
> We should remove these wrapper classes after Hadoop 3.3.2 release which
> should include the fix.
