Increasing storage capacity with HDFS compression

Linux supports GzipCodec, DefaultCodec, BZip2Codec, LzoCodec, and SnappyCodec. Typically, GzipCodec is used for HDFS compression.

To configure data compression, you can either enable a data compression codec, for example, GZipCodec, as the default or use the codec from the command line with a one-time job.
