Dmytro Molkov updated HDFS-94:
------------------------------
Attachment: HDFS-94.patch
This patch uses JMX Memory beans instead of runtime.
I was talking to Dhruba, he mentioned we might want to do this JIRA as a
bugfix, so that it can be pulled into 21 and displaying more information can be
a separate 'improvement' JIRA.

> Heap Size is 10.01 GB / 10.01 GB (100%)
