> 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.
