Todd Lipcon commented on HIVE-842:
----------------------------------
Hey Pradeep. Those changes seem reasonable. I'm not personally a fan of the
"login user" concept in Hadoop security - it's static state, which prevents
servers which may want to use multiple principals from doing so easily (eg if
running a hive server with an embedded metastore, you may need a different
principal for the two different pieces). But given that there is no "renewer"
thread for non-loginuser keytab logins, it may be the only choice for now.
