--------------------------------------------
Summary: Introducing resource request types
Key: YARN-4335
URL: https://issues.apache.org/jira/browse/YARN-4335
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Konstantinos Karanasos
Assignee: Konstantinos Karanasos
YARN-2882 introduced container types that are internal (not user-facing) and
are used by the ContainerManager during execution at the NM.
With this JIRA we are introducing (user-facing) resource request types that are
used by the AM to specify the type of the ResourceRequest.
We will initially support two resource request types: CONSERVATIVE and
OPTIMISTIC.
CONSERVATIVE resource requests will be handed internally to containers of
GUARANTEED type, whereas OPTIMISTIC resource requests will be handed to
QUEUEABLE containers.
