             Summary: Validation of file after distcp in repl load 
                 Key: HIVE-16898
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
    Affects Versions: 3.0.0
            Reporter: anishek
            Assignee: anishek
             Fix For: 3.0.0

time between deciding the source and destination path for distcp to invoking of distcp can
have a change of the source file, hence distcp might copy the wrong file to destination, hence
we should an additional check on the checksum of the source file path after distcp finishes
to make sure the path didnot change during the copy process. if it has take additional steps
to delete the previous file on destination and copy the new source and repeat the same process
as above till we copy the correct file.
