> Key: HIVE-17289
> URL: https://issues.apache.org/jira/browse/HIVE-17289
> Project: Hive
> Issue Type: Sub-task
> Components: HiveServer2, repl
> Affects Versions: 3.0.0
> Reporter: Sankar Hariappan
> Assignee: Sankar Hariappan
> Labels: DR, Import, replication
> Fix For: 3.0.0
>
>
> Currently, 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 IMPORT flow.
> Also, need to set the default config for hive.distcp.privileged.doAs to
> "hive" as "hdfs" super-user is never allowed.
