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

             Summary: Reuse DataChecksum
                 Key: HBASE-16717
                 URL: https://issues.apache.org/jira/browse/HBASE-16717
             Project: HBase
          Issue Type: Improvement
            Reporter: binlijin
            Priority: Minor


Every time to generateChecksums or validateChecksum will create a new 
DataChecksum, and DataChecksum is not thread safe, so use ThreadLocal to reuse 
it and keep thread safe.
