Sumit Mohanty commented on AMBARI-1865:
---------------------------------------

Will this be safe?
{code}
SELECT MAX(config_tag)
{code}

Is tag supposed to be ordered such that max is the correct one. I thought one 
can put arbitrary tags when using API directly. Is MAX of the timestamp more 
reliable?

Rest looks good.
