> Key: HADOOP-12007

> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Yejun Yang

> org/apache/hadoop/io/compress/GzipCodec.java call CompressionCodec.Util.createOutputStreamWithCodecPool to use CodecPool. But compressor objects are actually never returned to pool which cause memory leak.
> HADOOP-10591 uses CompressionOutputStream.close() to return Compressor object to pool. But CompressionCodec.Util.createOutputStreamWithCodecPool actually returns a CompressorStream which overrides close().
> This cause CodecPool.returnCompressor never being called. In my log file I can see lots of "Got brand-new compressor [.gz]" but no "Got recycled compressor".
