------------------------------------
Summary: Proactively relocate allocated containers from a stopped
node
Key: YARN-10357
URL: https://issues.apache.org/jira/browse/YARN-10357
Project: Hadoop YARN
Issue Type: Improvement
Components: multi-node-placement, capacityscheduler
Affects Versions: 3.4.0
Reporter: Prabhu Joseph
Assignee: Prabhu Joseph
In a cloud environment, node can be frequently commissioned, if we always wait
for 10 mins timeout, it may not be good, it's better to improve the logic by
preempting containers newly allocated (by not acquired) on NM which stopped
heartbeating. With this, we can proactively relocate containers to different
nodes before the 10 mins timeout.
