Sunil G commented on YARN-2293: ------------------------------- Hi [~zjshen] This work is moved to YARN-2005, I will share a basic prototype soon in that. This can be made as duplicated to YARN-2005. > 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 (v6.3.4#6332)
