Subject [jira] [Created] (HDFS-4224) The dncp_block_verification log can be compressed
Date Mon, 26 Nov 2012 14:38:58 GMT
Harsh J created HDFS-4224:

             Summary: The dncp_block_verification log can be compressed
                 Key: HDFS-4224
                 URL: https://issues.apache.org/jira/browse/HDFS-4224
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node
    Affects Versions: 2.0.0-alpha
            Reporter: Harsh J
            Priority: Minor

On some systems, I noticed that when the scanner runs, the dncp_block_verification.log.curr
file under the block pool gets quite large (several GBs). Although this is rolled away, we
could also configure compression upon it (a codec that may work without natives, would be
a good default) and save on I/O and space.
