Description

The web UI on the RM for the link Nodes shows that Health-report as null when the NM is healthy.

This is a simple fix where in we can check for null in NodesPage.java and put something meaningful instead of null.
NodesPage.java:

render(..)

td((health.getHealthReport() == null) ?"REPORT HEALTHY": health.getHealthReport());

Or something like that.
