---------------------------------
Summary: [Umbrella] Add support for YARN Allocation composed of
multiple containers/processes
Key: YARN-5593
URL: https://issues.apache.org/jira/browse/YARN-5593
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Arun Suresh
Assignee: Arun Suresh
Opening this to explicitly call out and track some of the ideas that were
discussed in YARN-1040. Specifically the concept of an {{Allocation}} which can
be used by an AM to start multiple {{Containers}} against as long as the sum of
resources used by all containers {{fitsIn()}} the Resources leased to the
{{Allocation}}.
This is especially useful for AMs that might want to target certain operations
(like upgrade / restart) on specific containers / processes within an
Allocation without fear of losing the allocation.
