Review request for Ambari, Myroslav Papirkovskyy and Sid Wagle.


Bugs: AMBARI-13161
    https://issues.apache.org/jira/browse/AMBARI-13161


Repository: ambari


Description
-------

stack advisor allocated 713m to Master and 1024m to RS, in distributed mode. For small clusters
we should default to 512m Master, RS should get as much memory as possible.
In distributed mode we should WARN if no DN is local and set dfs.client.read.shortcircuit
= true in ams-hbase-site if local DN is present
