---------------------------------------
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.
