Subject [jira] Created: (HBASE-2225) Enable compression in HBase Export
Date Sat, 13 Feb 2010 15:46:28 GMT
Enable compression in HBase Export

                 Key: HBASE-2225
                 URL: https://issues.apache.org/jira/browse/HBASE-2225
             Project: Hadoop HBase
          Issue Type: Improvement
          Components: util
    Affects Versions: 0.20.1
         Environment: OS agnostic
            Reporter: Ted Yu
            Priority: Minor

org.apache.hadoop.hbase.mapreduce.Export should set compression codec

In createSubmittableJob(), the following should be added:
    FileOutputFormat.setCompressOutput(job, true);
    FileOutputFormat.setOutputCompressorClass(job, org.apache.hadoop.io.compress.GzipCodec.class);

>From my experiment, 10% to 50% reduction in Export output has been observed.

SequenceFileInputFormat used by the Import tool is able to detect GzipCodec - there is no
change for Import class.
