Date Wed, 30 Sep 2009 15:07:23 GMT
Compression test utility
------------------------

                 Key: HBASE-1875
                 URL: https://issues.apache.org/jira/browse/HBASE-1875
             Project: Hadoop HBase
          Issue Type: New Feature
          Components: util
    Affects Versions: 0.20.0
            Reporter: elsif 
            Priority: Trivial
             Fix For: 0.20.1


Attached is a stand alone utility to test compression compatibility
before starting hbase:

# ./hbase org.apache.hadoop.hbase.test.HFileCompressionTest
Usage: HFileCompressionTest hdfs compression
  compression must be one of [ none, gz, lzo ]

# ./hbase org.apache.hadoop.hbase.test.HFileCompressionTest
hdfs://localhost:8020/ lzo
09/09/29 13:39:55 INFO lzo.GPLNativeCodeLoader: Loaded native gpl library
09/09/29 13:39:55 INFO lzo.LzoCodec: Successfully loaded & initialized
native-lzo library
09/09/29 13:39:55 INFO compress.CodecPool: Got brand-new compressor
OK

The utility creates a temporary HFile named '.hfile-comp-test' at the
specified HDFS path and outputs either 'OK' or 'FAILED'.
