------------------------------
Summary: Improve implicit task history pruning (was: Improve task history
pruning)
> Improve implicit task history pruning
> -------------------------------------
>
> Key: AURORA-1837
> URL: https://issues.apache.org/jira/browse/AURORA-1837
> Project: Aurora
> Issue Type: Task
> Reporter: Reza Motamedi
> Assignee: Mehrdad Nurolahzade
> Priority: Minor
> Labels: scheduler
>
> Current implementation of {{TaskHistoryPrunner}} registers all inactive tasks
> upon terminal _state_ change for pruning.
> {{TaskHistoryPrunner::registerInactiveTask()}} uses a delay executor to
> schedule the process of pruning _task_s. However, we have noticed most of
> pruning takes place after scheduler recovers from a fail-over.
> Modify {{TaskHistoryPruner}} to a design similar to
> {{JobUpdateHistoryPruner}}:
> # Instead of registering delay executor's upon terminal task state
> transitions, have it wake up on preconfigured intervals, find all terminal
> state tasks that meet pruning criteria and delete them.
> # Make the initial task history pruning delay configurable so that it does
> not hamper scheduler upon start.
