---------------------------------
Summary: 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: Jakob Homan
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.
