Review request for Ambari, Myroslav Papirkovskyy and Vitalyi Brodetskyi.


Bugs: AMBARI-12825
    https://issues.apache.org/jira/browse/AMBARI-12825


Repository: ambari


Description
-------

In the Ambari Host views it says the CPU is under 3%, but yet if you perform a 'sar 10 10' you can easily see its over 75%. Any ideas? This is during the middle of a Terasort job so its taking over 100% of the cluster and had been running for over a minute before measurements were taken.
