> TezTask reopen relies on getting the same session object in terms of setup; WM reopen
returns a new session from the pool. 
> The former has the advantage of not having to reupload files and stuff... but the object
reuse results in a lot of ugly code, and also reopen might be slower on average with the session
pool than just getting a session from the pool. Either WM needs to do the object-preserving
reopen, or TezTask needs to be refactored. It looks like DAG would have to be rebuilt to do
the latter because of some paths tied to a directory of the old session. Let me see if I can
get around that; if not we can do the former; and then if the former results in too much ugly
code in WM to account for object reuse for different Tez client I'd do the latter anyway since
it's a failure path :)
