> 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:
> {code}
> render(..)
> td((health.getHealthReport() == null) ?"REPORT HEALTHY":
> health.getHealthReport());
> {code}
> Or something like that.
