> Key: HELIX-795
> URL: https://issues.apache.org/jira/browse/HELIX-795
> Project: Apache Helix
> Issue Type: Improvement
> Reporter: Hunter L
> Assignee: Hunter L
> Priority: Major
>
> This changes the default reset() behavior for tasks on Participants.
> Previously, it would send all task partitions to INIT. After this change, the
> task partitions will inherit the states from the previous session, and their
> RequestedState will be set to DROPPED. Then the Controller will send messages
> to drop the said task partitions so that there are no quota/resource leaks
> for the number of tasks on Participants.
> Changelist:
> 1. Modify state transition logic so that drop state transitions messages
> will be honored
> 2. Modify CurrentState copy-over logic
> 3. Add an integration test: TestDropOnParticipantReset
