Description

As part of HIVE-17512 we fixed the distCp user impersonation if doAs = false and configured "hive.distcp.privileged.doAs" is same as the user running hiveServer. However in the event of not applying the source in patch for HIVE-17512 and running the corresponding test run in HIVE-17512 with older code there is impersonation error in the hive server logs, however the driver returns an "exitValue" of 0 which is wrong, since the copy failed we should return the error code appropriately.

also since the table creation happens and only data is missing there is a possibility that the last.repl.id on the table is the latest value with the data missing and coupled with no error returned to the client this can lead to serious replication inconsistencies.
