[~hitesh], Is this still valid now ? sending V_INIT to downstream after vertex is initialized make more sense and will make the state machine easy to understanding. I think we should we either fix this or rename numInitedSourceVertices to numInitStartedSourceVertices, otherwise it is a little confusing.

> Current impl sends V_INIT event even though the vertex may be initializing itself. Downstream vertices may be dependent on initialized info of upstream. 
> Related fix in recovery for TEZ-998 should be reverted as part of this jira.
