Thanks @kevins-29 , the fix looks good to me. However, is this addressing
the issue mentioned in HADOOP-12007? my understanding is that the issue there
is related to `CompressorStream` overrides `close` and doesn't return the
compressor to the pool as result.

> 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
