Subroto Sanyal commented on MAPREDUCE-2990:
-------------------------------------------
Hi Vinod/Mahadev,
In case if node is healthy, the node page table will look something like this:
||Rack||Node Address||Node HTTP Address||Health-status||Last
health-update||Health-report|| Containers ||
|/default-rack|10.18.52.110:45454|10.18.52.110:9999|Healthy|23-Sep-2011
14:12:58|Healthy||
Both the Columns *Health-Status* and *Health-Report* will display the node as
Healthy in case is Node is running fine. Is it OK to have same text in both
columns or we can have no text in second column if *Health-Status* is *Healthy*?
> 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.
