Review request for Ambari, Alejandro Fernandez and Sumit Mohanty.


Bugs: AMBARI-18724
    https://issues.apache.org/jira/browse/AMBARI-18724


Repository: ambari


Description
-------

**Issue**
'hive.llap.zk.sm.connectionString' doesn't get updated when we upgrade from HDP 
2.4 -> 2.5, and continues to have default value 'localhost:2181'.


**Analysis:**
As there is no dependency defined for the configs to get updated, Stack Advisor 
and/or UI will filter applying the sugested change by the Stack Advisor code.  
Thats the reason even if SA code suggests the correct configs value, its never 
applied.


**Fix**
Added a dependency of HSI config 'hive.llap.zk.sm.connectionString' on 
'enable_hive_interactive', so that 'hive.llap.zk.sm.connectionString' gets 
updated.
