-----------------------------

             Summary: If java7, use zip crc
                 Key: HBASE-11927
                 URL: https://issues.apache.org/jira/browse/HBASE-11927
             Project: HBase
          Issue Type: Bug
            Reporter: stack
            Assignee: stack
             Fix For: 0.99.1


Up in hadoop they have this change. Let me publish some graphs to show that it makes a difference
(CRC is a massive amount of our CPU usage in my profiling of an upload because of compacting,
flushing, etc.).  We should also make use of native CRCings -- especially the 2.6 HDFS-6865
and ilk -- in hbase but that is another issue for now.
