---------------------------------------
Summary: IMPORT should copy files without using doAs user.
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
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.
