Subject [jira] [Created] (YARN-2293) Scoring for NMs to identify a better candidate to launch AMs

-----------------------------

             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?
