> 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. The issue with using distcp for this is that distcp
> launches from another job which may be queued on another machine, which does
> not have access to this file:// uri. Distcp should only ever be used when
> copying from non-localfilesystems.
> 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.
