-----------------------------------

Looks like YARN-7371 is already handling this.

> We have added a mapping of the allocated container to the original request through YARN-4887/YARN-4888.
There is a corner case in which the mapping will be lost, i.e. if RM fails over before notifying
the AM about newly allocated container(s). This JIRA tracks the changes required to include
the allocationRequestId in NMContainerStatus to allow recovery in case of RM failover.
