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.
