The Heap Size printed in the JobTracker WebUI is accurate
Description
1.0 JobTracker's jobtracker.jsp page currently shows:
<h2>Cluster Summary (Heap Size is <%= StringUtils.byteDesc(Runtime.getRuntime().totalMemory()) %>/<%= StringUtils.byteDesc(Runtime.getRuntime().maxMemory()) %>)</h2>
It could use an improvement same as HDFS-94 to reflect live heap usage more accurately.
