Aaron Kimball updated HADOOP-6315:
----------------------------------
Attachment: HADOOP-6315.patch
GzipCodec does not use BuiltInZlibInflater as its decompressor;
createDecompressor() returns null. But getDecompressorType() returns
BuiltInZlibInflater as its inflater type, which causes CodecPool to use
BuiltInZlibInflater for GzipCodec.getDecompressor(). This inflater does not
work on .gz files.
This patch fixes the bug. Also includes two test cases that demonstrate the
problem.
> GzipCodec should not represent BuiltInZlibInflater as decompressorType
