Bikas Saha commented on TEZ-1247:
---------------------------------

The DAG already has builder pattern. This jira is to replace the constructor 
with a creator.
The verify method is public only for testing. If that is not needed then we 
should remove the public or at least mark it @private. The flow is supposed to 
be to add all the vertices and edge and then pass it to TezClient. TezClient 
calls createDAG and submits the job.

> Method verify() of DAG can't been called multiples times in some cases
