Bikas Saha commented on YARN-2047: ---------------------------------- I think the general idea is that the AM cannot be trusted about allocated resources or running containers. > RM should honor NM heartbeat expiry after RM restart > ---------------------------------------------------- > > Key: YARN-2047 > URL: https://issues.apache.org/jira/browse/YARN-2047 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Reporter: Bikas Saha > > After the RM restarts, it forgets about existing NM's (and their potentially > decommissioned status too). After restart, the RM cannot maintain the > contract to the AM's that a lost NM's containers will be marked finished > within the expiry time. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
