----------------------------
Assignee: Jaume M
> add ability to pass information between plugins
> -----------------------------------------------
>
> Key: TEZ-3866
> URL: https://issues.apache.org/jira/browse/TEZ-3866
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Sergey Shelukhin
> Assignee: Jaume M
> Priority: Major
>
> Distinct from TEZ-3815, since even with a hack that makes plugins aware of
> each other, they cannot store task-specific info without calling into each
> others' per-task structures.
> In particular, I need a piece of info that is generated when the custom
> scheduler calls getContext().taskAllocated, to be propagated to communicator
> plugin registerRunningTaskAttempt, so that the custom communicator could
> include additional info in task submission (e.g. a scheduler-specific
> priority or other instructions). There doesn't seem to be any means to do it
> now.
