Review request for Ambari and Andrew Onischuk.


Bugs: AMBARI-12217
    https://issues.apache.org/jira/browse/AMBARI-12217


Repository: ambari


Description
-------

Yarn service check today runs a distributed shell application with num_containers = num_nodes_in_cluster.
This could be a problem on production cluster because the num_nodes could be very large, therefore
the service check may run slow. 
We may just change it back to launch 1 container.
