Sergey Shelukhin updated HIVE-13391:
------------------------------------
    Attachment: HIVE-13391.patch

[~sseth] can you review this, esp. the Tez-related parts? This adds the keytab 
setting that is used from Tez where it calls the record reader, and from IO 
elevator. I am actually not sure IO elevator path is even necessary in this 
case, cause it already takes current user UGI, and we could assume the Tez path 
would set this correctly.


> add an option to LLAP to use keytab to authenticate to read data
