-------------------------------------------
Hi Harsh, thanks for looking this.
I remember i have seen this in trunk and also corrected some tests along with
HDFS-1765. After that i don't see any failures in TestNAmeNodeMetrics. I am
just closing this as con't reproduce ( again i ran 4 times this test for
reconfirmation.).
