[jira] [Created] (HBASE-7435) BuiltInGzipDecompressor is only released during full GC

Lars Hofhansl created HBASE-7435:
------------------------------------

             Summary: BuiltInGzipDecompressor is only released during full GC
                 Key: HBASE-7435
                 URL: https://issues.apache.org/jira/browse/HBASE-7435
             Project: HBase
          Issue Type: Bug
            Reporter: Lars Hofhansl
             Fix For: 0.96.0, 0.94.4


That seems to be bug in Hadoop, actually.

BuiltInGzipDecompressor.end() needs to be called to release it's resource, but it is not called anywhere in CodecPool.
Instead the end() is called by finalize(), which is only called during a full gc (or never, depending on JVM).

This is only an issue in test. In real life most folks will have the native GzipDecompressor
