[jira] [Commented] (YARN-8036) Memory Available shows a negative
value after running updateNodeResource
[ https://issues.apache.org/jira/browse/YARN-8036?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16535649#comment-16535649 ]
Zian Chen commented on YARN-8036:
---------------------------------
Hi [~charanh] , can you please provide the detailed steps how to reproduce this issue? Like how much resource(memory, Vcores, etc) this application already used, and what's the pending resource, etc.
Are we using multiple resources here? If yes, this might be an issue with DRC. We recently observed several DRC issues very similar to this one.

> Running updateNodeResource for a node that already has applications running on it doesn't update Memory Available with the right values. It may end up showing negative values based on the requirements of the application. Attached a screenshot for reference.
