Bugs: AMBARI-17983
    https://issues.apache.org/jira/browse/AMBARI-17983


Repository: ambari


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.
