> 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.
