--------------------------------
Summary: Support intra-queue non-exclusive container allocation
within a LeafQueue
Key: YARN-3515
URL: https://issues.apache.org/jira/browse/YARN-3515
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Wangda Tan
Assignee: Wangda Tan
Related to YARN-2498:
YARN-2498 addressed the problem of non-exclusive container preemption in
inter-queue level. When a queue over-satisfied on a given partition,
ignore_partition_exclusivity containers will be preempted first.
But it is possible that when a queue is under its guaranteed resource, there's
pending resources for a given partition, and resources being used by
ignore_partition_exclusivity containers. For example:
- App1/App2 in queue-A, app1 wants 30 partition=x containers and app2 uses 30
partition=x ignore_partition-exclusivity containers. It is possible we need
reclaim resource from app2 for partition=x.
Relation between this and YARN-2498 is similar to relation between YARN-2069
and YARN-2113.
