Brahma Reddy Battula commented on HDFS-8116:
--------------------------------------------

[~andrew.wang] ,it's better to remove {{LOG.isDebugEnabled()}} as [~xyao] 
pointed which makes consistency in {{RollingWindowManager}} ..if you agree, i 
will chage defect summary and give patch..

> RollingWindowManager#getTopUserForMetric should check if LOG.isDebugEnabled() 
> before LOG.debug()
