Subject [jira] [Created] (HIVE-16918) Skip ReplCopyTask distcp for _metadata copying. Also enable -pb for distcp

Sushanth Sowmyan created HIVE-16918:
---------------------------------------

             Summary: Skip ReplCopyTask distcp for _metadata copying. Also enable -pb for
distcp
                 Key: HIVE-16918
                 URL: https://issues.apache.org/jira/browse/HIVE-16918
             Project: Hive
          Issue Type: Bug
          Components: repl
    Affects Versions: 3.0.0
            Reporter: Sushanth Sowmyan
            Assignee: Sushanth Sowmyan


With HIVE-16686, we switched ReplCopyTask to always use a privileged DistCp. This, however,
is incorrect for copying _metadata generated from a temporary scratch directory to hdfs. We
need to change that so that routes to using a regular CopyTask.

Also, in the spirit of following up HIVE-16686, we missed adding "-pb" as a default for invocations
of distcp from hive. Adding that in. This would not be necessary if HADOOP-8143 had made it
in, but till it doesn't go in, we need it.
