> allow plugins to be aware of each other

> Key: TEZ-3815
> URL: https://issues.apache.org/jira/browse/TEZ-3815
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Sergey Shelukhin
>
> Given that many sets of plugins (e.g. LLAP) come as a package deal and do not
> work without each other, it would make sense for them to be aware of each
> other.
> Not sure yet of the best way for this to work, we probably don't want too
> much complexity, dependency systems, etc. Perhaps after all the plugins are
> initialized fully, an optional-to-implement call could be made to each of
> them passing a map from plugin type (communicator, scheduler, etc.) to the
> instance that is going to be used for this DAG.
