Tsz Wo (Nicholas), SZE commented on HDFS-94:
--------------------------------------------

It makes to replace the current codes by MemoryMXBean since it provides more information.  I think it is better to show more numbers like non-heap usage, init, used, committed, max, etc.

> It seems that the Heap Size shown in HDFS web UI is not accurate.  It keeps showing 100% of usage.  e.g.
> {noformat}
> Heap Size is 10.01 GB / 10.01 GB (100%) 
> {noformat}
