Bikas Saha commented on TEZ-1210:
---------------------------------
The DAGPlan is downloaded as a local resource to be used to run the DAG. In
session mode the AM is already running and can accept the DAGPlan over RPC. In
non-session mode is going to be launched (and there is no connection between it
and the client) and thus the DAGPlan needs to be provides indirectly as a YARN
LocalResource via HDFS.
> TezClientUtils.localizeDagPlanAsText() needs to be fixed for session mode

> It writes the dagPlan in text form to the same location. Either it should not
> be invoked in session mode or it should written with a differentiating prefix.
