--------------------------------
Status: Patch Available (was: Open)
> Memory leak when reading a compressed file using the native library
> -------------------------------------------------------------------
>
> Key: HADOOP-14376
> URL: https://issues.apache.org/jira/browse/HADOOP-14376
> Project: Hadoop Common
> Issue Type: Bug
> Components: common, io
> Affects Versions: 2.7.0
> Reporter: Eli Acherkan
> Assignee: Eli Acherkan
> Attachments: Bzip2MemoryTester.java, HADOOP-14376.001.patch,
> log4j.properties
>
>
> Opening and closing a large number of bzip2-compressed input streams causes
> the process to be killed on OutOfMemory when using the native bzip2 library.
> Our initial analysis suggests that this can be caused by
> {{DecompressorStream}} overriding the {{close()}} method, and therefore
> skipping the line from its parent:
> {{CodecPool.returnDecompressor(trackedDecompressor)}}. When the decompressor
> object is a {{Bzip2Decompressor}}, its native {{end()}} method is never
> called, and the allocated memory isn't freed.
> If this analysis is correct, the simplest way to fix this bug would be to
> replace {{in.close()}} with {{super.close()}} in {{DecompressorStream}}.
