Sankar Hariappan updated HIVE-17289:
------------------------------------
Description:
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.
