[jira] [Created] (YARN-5289) Use checksum in localisation requests

Yesha Vora created YARN-5289:
--------------------------------

             Summary: Use checksum in localisation requests
                 Key: YARN-5289
                 URL: https://issues.apache.org/jira/browse/YARN-5289
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Yesha Vora


Currently, timestamps is being used in  localization requests. Because using timestamps is always pretty brittle. ( we notice a clock jump in the VM.)

For the filesystem supporting getFileChecksum(Path), the checksum can be used instead of timestamps in localisation requests
