-------------------------------
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?
