[jira] [Commented] (YARN-7102) NM heartbeat stuck when responseId
overflows MAX_INT
[ https://issues.apache.org/jira/browse/YARN-7102?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16310045#comment-16310045 ]
Botong Huang commented on YARN-7102:
------------------------------------
Hi [~jlowe], in v15 patch I moved part of the reconnect logic into ResourceTrackerService.registerNodeManager as you suggested. The specific condition where we replace with a new RMNode is a bit weird though. Reading the original code in ReconnectNodeTransition, various conditions about when to swap the node and when to call NodeResourceUpdateSchedulerEvent seems inconsistent. I am wondering if it is possible to always not swap and use the existing RMNode. Please let me know what you think, thanks!
