> 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).
