Sangjin Lee commented on HADOOP-9317:
-------------------------------------

There has been no movement on this for a while. We'll need to move it out of scope for 2.8.0
soon. Let me know if you disagree.

> {{UserGroupInformation}} only allows kerberos users to be logged in via the ticket cache
when running hadoop commands.  {{UGI}} allows a keytab to be used, but it's only exposed programatically.
 This forces keytab-based users running hadoop commands to periodically issue a kinit from
the keytab.  A race condition exists during the kinit when the ticket cache is deleted and
re-created.  Hadoop commands will fail when the ticket cache does not momentarily exist.
