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.
> The "Heap Size" in HDFS web ui may not be accurate

> 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}
