Hitesh Shah commented on TEZ-1008:
----------------------------------
I dont think this was fixed. One reason was performance. Not sending a V_INIT
means that a downstream vertex cannot start initializing. In some cases,
initialization ( large no. of splits ) can take a long time.
> Vertex V_INIT should be sent to downstream vertices only after vertex is
> initialized

> Key: TEZ-1008
> URL: https://issues.apache.org/jira/browse/TEZ-1008
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Hitesh Shah
> Assignee: Rekha Joshi
>
> 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.
