---------------------------------
Summary: Add more states and transitions to stabilize the NM
Container state machine
Key: YARN-7240
URL: https://issues.apache.org/jira/browse/YARN-7240
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Arun Suresh
Assignee: kartheek muthyala
There seem to be a few intermediate states that can be added to improve the
stability of the NM container state machine.
For. eg:
* The REINITIALIZING should probably be split into REINITIALIZING and
REINITIALIZING_AWAITING_KILL.
* Container updates are currently handled in the ContainerScheduler, but it
would probably be better to have it plumbed through the container state machine
as a new state, say UPDATING and a new container event.
The plan is to add some extra tests too to try and test every transition.
