Bikas Saha commented on TEZ-1592:
---------------------------------
The root question is how did an initializer complete event come after
parallelism was set when split generation is happening in the AM. May be there
is an additional bug there. [~vikram.dixit] Can you please attach the stuck job
logs?
> Vertex should wait for all initializers to finish before moving to INITED
