Tsuyoshi OZAWA commented on YARN-2800: -------------------------------------- [~leftnoteasy], Thanks for your clarification. Essentially, the configurations about labels are a part of RM's state. IMHO, we should move the essential configuration onto RMStateStore to prevent the mismatch ideally. I think ZK can handle it since frequency of updating labels is not so high and number of labels are not so large. cc: [~jianhe], [~kkambatl], what do you think? > Should print WARN log in both RM/RMAdminCLI side when > MemoryRMNodeLabelsManager is enabled > ------------------------------------------------------------------------------------------ > > Key: YARN-2800 > URL: https://issues.apache.org/jira/browse/YARN-2800 > Project: Hadoop YARN > Issue Type: Sub-task > Components: client, resourcemanager > Reporter: Wangda Tan > Assignee: Wangda Tan > Attachments: YARN-2800-20141102-1.patch, YARN-2800-20141102-2.patch > > > Even though we have documented this, but it will be better to explicitly > print a message in both RM/RMAdminCLI side to explicitly say that the node > label being added will be lost across RM restart. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
