Eric Yang commented on YARN-8160:
---------------------------------
Base on what I read from YARN-7973, the relaunch event is encapsulated in
ContainerLauncher. By passing parameter to ContainerLauncher event, it can
trigger relaunch of container to happen. Where YARN-7939 code have added a new
transition for relaunch in ContainerImpl, and trigger a new type of relaunch
event. The alignment can happen if we surface YARN-7973 logic from
ContainerLauncher and connect with the new transition event for doRelaunch. It
might help to refine relaunch logic and reuse some of the existing code.
