--------------------------------
Summary: Preserve execution type for containers to be promoted by
AM post YARN-1015
Key: YARN-7421
URL: https://issues.apache.org/jira/browse/YARN-7421
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: YARN-1011
Reporter: Haibo Chen
Assignee: Haibo Chen
>From offline discussion with [~asuresh], if an AM tries to promote or increase
>a container whose enforceExecutionType is set to false, the scheduler may, in
>the presence of oversubscription, allocate an OPPORTUNISTIC container. This
>should not happen given the contract we have in container update API.
