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

             Summary: optimization to give distcp a list of input files to copy to a destination target directory
                 Key: HIVE-16900
                 URL: https://issues.apache.org/jira/browse/HIVE-16900
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
    Affects Versions: 3.0.0
            Reporter: anishek
            Assignee: anishek
             Fix For: 3.0.0


During repl Copy currently we only allow operations per file as against list of files supported by distcp, During bootstrap table/partitions load it will be great to load all files listed in _files in a single distcp job to make it more efficient, this would require changes to the _shims_ sub project in hive to additionally expose api's which take multiple source files.
