Class NonBlockedDecompressorStream

java.lang.Object

java.io.InputStream

org.apache.hadoop.io.compress.CompressionInputStream

org.apache.hadoop.io.compress.DecompressorStream

All Implemented Interfaces:

Closeable, AutoCloseable, org.apache.hadoop.fs.Seekable

public class NonBlockedDecompressorStream
extends org.apache.hadoop.io.compress.DecompressorStream

DecompressorStream class that should be used instead of the default hadoop DecompressorStream 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.
