Daryn Sharp commented on HDFS-9072:
-----------------------------------

+1 but please file a new jira since this appears to loop forever waiting for the metric.  the 1s delay probably wastes a lot of runtime in the tests...

> There is a slight delay in updating the jmx values after HDFS operations. But assertions are done even that . Hence following testcases fails. 
>  TestJMXGet#testNameNode()
>  TestJMXGet#testDataNode()
