Swapan Shridhar updated AMBARI-17983:
-------------------------------------
    Description: 
(1). Revert AMBARI-16031 (Create "/hadoop/llap/local" on each host and disk in Kerberized
cluster for LLAP)
   
   - Earlier, we had logic for using YARN work dirs for LLAP by HIVE config 'hive.llap.daemon.work.dirs'
having same value as of YARN config 'yarn.nodemanager.local-dirs'.
   - In kerberized setup, we were creating separate directory for LLAP, where Hive user had
persmissions.
   
   
   - That is not required now, as HIVE is itself taking care of workdirs in kerberized and
un-kerberized environment. 
   - Thus, the revert.

(2). Remove the config 'hive.llap.daemon.work.dirs' as HIVE will manage the work directories
itself.
