Sreenath Somarajapuram commented on TEZ-3173:
---------------------------------------------
The events array property that comes from ATS. By default we get
VERTEX_INITIALIZED, VERTEX_STARTED & VERTEX_FINISHED.
But the UI is flexible enough to take in any number of events. Hence events
like VERTEX_PARALLELISM_UPDATED can also be send when available.
> Update Tez AM REST APIs to send back realtime events
