Sunil G created YARN-2293: ----------------------------- Summary: Scoring for NMs to identify a better candidate to launch AMs Key: YARN-2293 URL: https://issues.apache.org/jira/browse/YARN-2293 Project: Hadoop YARN Issue Type: Improvement Components: nodemanager, resourcemanager Reporter: Sunil G Assignee: Sunil G
Container exit status from NM is giving indications of reasons for its failure. Some times, it may be because of container launching problems in NM. In a heterogeneous cluster, some machines with weak hardware may cause more failures. It will be better not to launch AMs there more often. Also I would like to clear that container failures because of buggy job should not result in decreasing score. As mentioned earlier, based on exit status if a scoring mechanism is added for NMs in RM, then NMs with better scores can be given for launching AMs. Thoughts? -- This message was sent by Atlassian JIRA (v6.2#6252)
