Akira Ajisaka commented on YARN-3254:
-------------------------------------
bq. Would you mind if I take over this JIRA if you are not working on this
currently ?
No. You can take it over.
bq. Also, can you please explain why the patch is incompatible with jmx
information being changed ?
This health report is obtained from jmx. Accoding to the documentation
(https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Compatibility.html#MetricsJMX),
changing the jmx information breaks compatibility. Now I'm thinking you can
add the message to the Web UI if you create an additional jmx information and
use it.

> When a NodeManager's local disk gets almost full, the NodeManager sends a
> health report to ResourceManager that "local/log dir is bad" and the message
> is displayed on ResourceManager Web UI. It's difficult for users to detect
> why the dir is bad.
