Suma Shivaprasad commented on YARN-8488:
----------------------------------------
Attached patch which adds states SUCCEEDED to ServiceState, SUCCEEDED/FAILED to
ComponentState.
Earlier ComponentInstance State was marked as STOPPED for all available restart
policies. Now it is SUCCEEDED/FAILED depending on the exit status. One pending
issue is when there is a graceful stop sent via Client RPC, component instance
STATE is not marked as STOPPED. Will fix this in subsequent patch.
For restartPolicy=ON_FAILURE/NEVER, when all component instances terminate,
component = SUCCEEDED if all component instances succeed else marked as FAILED.
> Need to add "SUCCEED" state to YARN service

> Project: Hadoop YARN
> Issue Type: Task

> Existing YARN service has following states:
> {code}
> public enum ServiceState {
> ACCEPTED, STARTED, STABLE, STOPPED, FAILED, FLEX, UPGRADING,
> UPGRADING_AUTO_FINALIZE;
> }
> {code}
> Ideally we should add "SUCCEEDED" state in order to support long running
> applications like Tensorflow.
