Anubhav Dhoot created YARN-4180: ----------------------------------- Summary: AMLauncher does not retry on failures when talking to NM Key: YARN-4180 URL: https://issues.apache.org/jira/browse/YARN-4180 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Reporter: Anubhav Dhoot Assignee: Anubhav Dhoot
We see issues with RM trying to launch a container while a NM is restarting and we get exceptions like NMNotReadyException. While YARN-3842 added retry for other clients of NM (AMs mainly) its not used by AMLauncher in RM causing there intermittent errors to cause job failures. This can manifest during rolling restart of NMs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
