Anu Engineer commented on HDFS-10580:
-------------------------------------
+1, (Non-binding). Thank you for contributing this patch. I really appreciate
you taking time out to tune the output and look at the how noisy the logging
can be. Since this is used only in the planning phase these log statements will
not be part of any logs. So I guess it is okay to be little verbose if debug
flag is specified.

> There are two unused method {{skipVolume}} and {{printQueue}} in class
