[jira] [Created] (HDFS-15141) Support for getFileChecksum

Srinivasu Majeti created HDFS-15141:
---------------------------------------

             Summary: Support for getFileChecksum
                 Key: HDFS-15141
                 URL: https://issues.apache.org/jira/browse/HDFS-15141
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: ozone
            Reporter: Srinivasu Majeti


Support for getFileChecksum() and any other way to help distcp to avoid the copy of duplicate files even when the length is the same that of remote storage (cloud copy to s3). Checksum calculations of local ozone files should be better similar to whatever s3 is already doing/returning.
