Hitesh Shah commented on TEZ-2281:
----------------------------------
I think we have stayed clear of exposing Dag ID to users given that it is an
internal construct that does not need to be exposed to the user. It could be
exposed as a string identifier though from a logging perspective. Not sure if
we need to expose TezDAGID the object itself.

> DAGId can uniquely identify the dag. It can help to find out your dag on
> tez-ui and find its corresponding dag logs, although dag name can help it,
> but it is not unique, so should expose the dagId to users.
