Bikas Saha commented on TEZ-1170:
---------------------------------
bq. I think we need to fix at least the ROOT_INPUT_INITIALIZED state
transitions which were changed by this patch.
Do you mean this ?
bq. The shutdown is invoked as soon as a KILL comes in (which could be via a
user event). The Vertex processes the KILL and tries to shutdown the
initializers - however, some initialization_DONE events may be in queue or
generated if the initializer does not respect interrupts or wins a race between
the interrupt and completing.
You mean the code in TerminateInitingVertexTransition?
If yes, then it makes sense.

> After TEZ-1145 and 1151, a vertex should only need to stay in INITIALZING
> state when it has an uninitialized edge, or when the parallelism is at -1
> (not set yet). Waiting for all RootInputInitializers to complete should not
> be required - as long as one of them sets parallelism (via a VertexManager).
