Known Issues
- COMPX-18909:YARN NodeManagers potentially getting into unhealthy state caused by YARN-11709
- A logic was introduced to mark the NodeManager unhealthy if the container-executor encounters an unrecoverable or configuration error. For example, if the container-executor script is missing from the configured place. There is an edge-case in this behaviour that, if the application is killed just before one of the containers is trying to access the localizer syslog file, an IOException occurs because the NodeManager has already deleted the application log directory. This IOException is then catched by the logic of CDPD-49702/YARN-11709, and the NodeManager is marked unhealthy incorrectly.
