Review request for Ambari and Vitalyi Brodetskyi.


Bugs: AMBARI-5611
    https://issues.apache.org/jira/browse/AMBARI-5611


Repository: ambari


Description
-------

If YARN is not selected for installation, "start all services" phase fails
with

    
    
    
    Fail: Configuration parameter 'jobhistory_heapsize' was not found in configurations dictionary!
    

I think, jobhistory_heapsize parameter is used at mapred-env.sh template, that
is filled out when executing shared_initialization.py  
Probably moving population of mapred-env.sh template into YARN service scripts
would be the best solution.
