Subject [jira] [Commented] (HIVE-6907) HiveServer2 - wrong user gets used for metastore operation with embedded metastore
Date Tue, 15 Apr 2014 18:25:15 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6907?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13969856#comment-13969856

Thejas M Nair commented on HIVE-6907:
-------------------------------------

[~vaibhavgumashta] Also verified with a secure cluster that this patch works with doAs disabled
and no proxy entries for hive server2 user in core-site.xml . Thanks Vaibhav!
Also talked to [~jnp] (who has done lot of security work in core hadoop), this doAs as same
user does not require any proxy user entries.
So we have both experimental and theoretical validation! :)
