>
> Currently, EXPORT uses distcp to dump data files to dump directory and IMPORT
> uses distcp to copy the larger files/large number of files from dump
> directory to table staging directory. But, this copy fails as distcp is
> always done with doAs user specified in hive.distcp.privileged.doAs, which is
> "hdfs' by default.
> Need to remove usage of doAs user when try to distcp from EXPORT/IMPORT flow.
> Privileged user based distcp should be done only for REPL DUMP/LOAD commands.
> Also, need to set the default config for hive.distcp.privileged.doAs to
> "hive" as "hdfs" super-user is never allowed.
