------------------------------
Summary: User impersonation failure is not propagated by server as
a failure to client
Key: HIVE-17539
URL: https://issues.apache.org/jira/browse/HIVE-17539
Project: Hive
Issue Type: Bug
Components: HiveServer2
Affects Versions: 3.0.0
Reporter: anishek
Assignee: anishek
Priority: Critical
Fix For: 3.0.0
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.
