Bikas Saha updated TEZ-1547:
----------------------------
Attachment: TEZ-1547.1.patch
Uploading WIP patch that integrates the notifiers with the vertex managers.
Adds optional APIs to inform the vertex about planned reconfigurations when the
vertex is already fully configured. The helps clarify the auto-reduce case
where the vertex is fully configured but the ShuffleVertexManager may or may
not end up changing reconfiguring the vertex after that. Creates a new
notification about the vertex being fully configured so that listeners (like
downstream vertices) can know when the vertex is fully configured and they can
start their own work in case it will be affected by the reconfiguration.
> Make use of state change notifier in VertexManagerPlugins
