[jira] [Commented] (HIVE-13391) add an option to LLAP to use keytab to authenticate to read data

    [ https://issues.apache.org/jira/browse/HIVE-13391?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15267573#comment-15267573 ] 

Sergey Shelukhin commented on HIVE-13391:
-----------------------------------------

A different approach - clone the UGI. Solves both the token problem, and the undesirable FS object sharing. 
I filed HADOOP-13081 to add a proper API for this... I'll add reference to that in the TODO comment in the next iteration or on commit.
