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

             Summary: Avoid buffer coping in checksum verification
                 Key: HDDS-2204
                 URL: https://issues.apache.org/jira/browse/HDDS-2204

          Components: Ozone Client
            Reporter: Tsz-wo Sze

In Checksum.verifyChecksum(ByteString, ..), it first converts the ByteString to a byte array.  It lead to an unnecessary buffer coping.
