-------------------------------------
Summary: 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.
