Class ReusableStreamGzipCodec

java.lang.Object
  org.apache.hadoop.io.compress.DefaultCodec
      org.apache.hadoop.io.compress.GzipCodec
          org.apache.hadoop.hbase.io.compress.ReusableStreamGzipCodec

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, org.apache.hadoop.io.compress.CompressionCodec

@InterfaceAudience.Private
public class ReusableStreamGzipCodec
extends org.apache.hadoop.io.compress.GzipCodec

Fixes an inefficiency in Hadoop's Gzip codec, allowing to reuse compression streams.
