----------------------------------
Summary: LocalityMulticastAMRMProxyPolicy should handle cancel
request properly
Key: YARN-7339
URL: https://issues.apache.org/jira/browse/YARN-7339
Project: Hadoop YARN
Issue Type: Bug
Reporter: Botong Huang
Assignee: Botong Huang
Priority: Minor
Currently inside AMRMProxy, LocalityMulticastAMRMProxyPolicy is not handling
and splitting cancel requests from AM properly:
# For node cancel request, we should not treat it as a localized resource
request. Otherwise it can lead to all weight zero issue when computing
localized resource weight.
# For ANY cancel, we should broadcast to all known subclusters, not just the
ones associated with localized resources.
