[jira] [Commented] (YARN-9809) NMs should supply a health status
when registering with RM
[ https://issues.apache.org/jira/browse/YARN-9809?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16921741#comment-16921741 ]
Eric Badger commented on YARN-9809:
-----------------------------------
I propose adding a health status field to the NM-RM registration request. That way the NM can still register to the RM, but without getting a bunch of containers that will immediately get killed after the first heartbeat.

> Currently if the NM registers with the RM and it is unhealthy, it can be scheduled many containers before the first heartbeat. After the first heartbeat, the RM will mark the NM as unhealthy and kill all of the containers.
