> RM web page can not display NM's health report which is healthy
> ---------------------------------------------------------------
>
> Key: YARN-3059
> URL: https://issues.apache.org/jira/browse/YARN-3059
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.5.1
> Reporter: Wang Hao
>
> If the NM is healthy, it's health report can not display in RM web page.
> In function reportHealthStatus of NodeHealthMonitorExecutor, I found that if
> the HealthCheckerExitStatus is successful, the output was set to a empty
> string in function setHealthStatus.
> so，I change the code “setHealthStatus(true, "", now)” to
> “setHealthStatus(true,shexec.getOutput(), now)” . Then, the RM web page can
> display the NM's health report.
> Maybe set the output to a empty string can decrease the data that transfered
> between RM and NM. But I think we want to see the health report of NM in some
> cases.
