Bikas Saha commented on TEZ-2076:
---------------------------------

It would be good to add some basic sanity tests that verify that the in-memory 
model indeed matches the actual execution that happened. Having an e2e test 
that runs a job and then builds a model to verify accuracy would help. It would 
catch any regressions that may be caused by an update to the event writing code 
that does not make corresponding changes to this in-memory model.

> - Users should be able to download ATS data pertaining to a DAG from Tez-UI 
> (more like a zip file containing DAG/Vertex/Task/TaskAttempt info).
> - This can be plugged to an analyzer which parses the data, adds semantics 
> and provides an in-memory representation for further analysis.
> - This will enable to write different analyzer rules, which can be run on top 
> of this in-memory representation to come up with analysis on the DAG.
> - Results of this analyzer rules can be rendered on to UI (standalone webapp) 
> later point in time.
