jaehoon ko created YARN-4260: -------------------------------- Summary: Check NodeManager's validity based on hostname(IP) and port Key: YARN-4260 URL: https://issues.apache.org/jira/browse/YARN-4260 Project: Hadoop YARN Issue Type: Improvement Components: resourcemanager Affects Versions: 2.7.1 Reporter: jaehoon ko
There can be situations where multiple NMs are running on the same host; emulating multi-host YARN cluster on one host, deploying dockerized NMs that share network stack. In such cases, RM should be able to distinguish NMs running on the same host. However, current implementation checks validity of NM based only on hostname (NodesListManager.isValidNode()). So it is not possible to distinguish a specific NM from other NMs on the same host. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
