Yousef Abu-Salah reassigned YARN-10163: --------------------------------------- Assignee: Yousef Abu-Salah > Nodes with reused IP's will incorrectly maintain old label > ---------------------------------------------------------- > > Key: YARN-10163 > URL: https://issues.apache.org/jira/browse/YARN-10163 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Affects Versions: 2.8.5 > Reporter: Brandon Scheller > Assignee: Yousef Abu-Salah > Priority: Minor > > Take a long running cluster, where nodemanagers come and go as the number of > instances scale up and down. This can cause an issue with Yarn nodelabels > where an unlabeled node picks up the label of the previous node with a > matching ip. > In this scenario, node ip's could be reused and a new node could come up > taking the place of a previously labeled node. If the old node was labeled, > but the new node is not labeled, the new node will not send a node label > update and the old nodelabel will remain. This can cause issues as the node > now is mislabeled. > > The fix for this likely is to send node label updates even when a node is > unlabeled. This will allow the resourcemanger to reset the label to empty for > that node. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
