public class NonBlockedCompressorStream
extends org.apache.hadoop.io.compress.CompressorStream

CompressorStream class that should be used instead of the default hadoop CompressorStream object. Hadoop's compressor adds blocking ontop of the compression codec. We don't want that since our Pages already solve the need to add blocking.
