> Key: HELIX-808
> URL: https://issues.apache.org/jira/browse/HELIX-808
> Project: Apache Helix
> Issue Type: Improvement
> Reporter: Hunter L
> Assignee: Hunter L
> Priority: Major
>
> It was observed that TestNoDoubleAssign was failing intermittently. Upon
> debugging with more detailed logs, there was a race condition between newly
> starting tasks and dropping tasks. To prevent this, dropping state
> transitions will be prioritized and prevInstanceToTaskAssignment will be
> built from CurrentStates. This is needed to make sure the right number of
> tasks are assigned every task pipeline and dropping transitions happen right
> away.
>
> Changelist:
> 1\. Change the logic for generating prevInstToTaskAssignment so that it's
> based on CurrentState
> 2\. Add a special check for not updating task partition state upon
> Participant connection loss
> 3\. TestNoDoubleAssign passes consistently
> 4. Fix TestNoDoubleAssign so that there won't be any thread leak
