[jira] [Created] (AMBARI-5611) Datanode and other components fail to start without YARN installed

Andrew Onischuk created AMBARI-5611:
---------------------------------------

             Summary: Datanode and other components fail to start without YARN installed
                 Key: AMBARI-5611
                 URL: https://issues.apache.org/jira/browse/AMBARI-5611
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 1.6.0


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.
