sandflee created YARN-3987: ------------------------------ Summary: am container complete msg ack to NM once RM receive it Key: YARN-3987 URL: https://issues.apache.org/jira/browse/YARN-3987 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Reporter: sandflee
In our cluster we set max-am-attempts to a very very large num, and unfortunately our am crash after launched, leaving too many completed container(AM container) in NM. completed container is removed from NM and NMStateStore only if container complete is passed to AM, but if AM couldn't be launched, the completed AM container couldn't be cleaned, and may eat up NM heap memory. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
