                 Key: MAPREDUCE-2990
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2990
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: mrv2
    Affects Versions: 0.23.0
            Reporter: Mahadev konar


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(..)

th(health.getHealthReport()?"REPORT HEALTHY": health.getHealthReport);

{code}
Or something like that.
