Sergey Shelukhin commented on HIVE-13391:
-----------------------------------------
[~sseth] the problem is that you actually need to log in from keytab in the
first place, and doAs somewhere, to be authenticated, as far as I can tell.
Don't you? Does Tez runtime already login from keytab somewhere above
TezProcessor? I suspect current user will have tokens but no keytab.
> add an option to LLAP to use keytab to authenticate to read data
