Class SnappyCodec

java.lang.Object

org.apache.hadoop.hbase.io.compress.aircompressor.SnappyCodec

All Implemented Interfaces:

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

@InterfaceAudience.Private
public class SnappyCodec
extends Object
implements org.apache.hadoop.conf.Configurable, org.apache.hadoop.io.compress.CompressionCodec
