[jira] [Created] (TEZ-3866) add ability to pass information between plugins

Sergey Shelukhin created TEZ-3866:
-------------------------------------

             Summary: 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


Distinct from TEZ-3815, since even with the 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. There doesn't seem to be any means to do it now.
