Review request for Ambari, Sid Wagle and Tom Beerbower.


Bugs: AMBARI-6263
    https://issues.apache.org/jira/browse/AMBARI-6263


Repository: ambari


Description
-------

On a large cluster, calls to /hosts are taking more than 30 seconds.
This severely impacts the responsiveness of the UI for the Hosts page (it takes > 30 seconds
to filter, navigate through paged hosts, etc).
The times shown are latency only (does not include download time).
