Vinod Kumar Vavilapalli updated MAPREDUCE-2990:
-----------------------------------------------
Assignee: (was: Sanjay Radia)
NodeManager shouldn't be passing null health. ever. This null-check done in the
patch may be hiding some real bug somewhere. Can you please investigate? You
can look in NodeStatusUpdaterImpl and ResourceTrackerService. Thanks!
> Health Report on Resource Manager UI is null if the NM's are all healthy.

> 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.
