Assignee: Chris Riccomini (was: Jakob Homan)
> Provide AM based antiaffinity to avoid clumping of containers
> -------------------------------------------------------------
>
> Key: SAMZA-124
> URL: https://issues.apache.org/jira/browse/SAMZA-124
> Project: Samza
> Issue Type: Improvement
> Components: container
> Affects Versions: 0.6.0
> Reporter: Jakob Homan
> Assignee: Chris Riccomini
> Fix For: 0.7.0
>
>
> We're seeing YARN scheduling lots of containers on the same box causing NIC
> saturation and cluster degradation. Pending SAMZA-74 (and its dependency,
> YARN-1042), it would be good to have some basic anti-affinity support at the
> AM level. We can be selective about what nodes we request and accept from
> the RM, hopefully spreading the containers around the cluster more evenly.
