> When tez print summary is enabled, methods summary is printed which are
> difficult to correlate with the actual execution time. We can improve that to
> print the execution times in the sequence of operations that happens behind
> the scenes.
> Instead of printing the methods name it will be useful to print something
> like below
> 1) Query Compilation time
> 2) Query Submit to DAG Submit time
> 3) DAG Submit to DAG Accept time
> 4) DAG Accept to DAG Start time
> 5) DAG Start to DAG End time
> With this it will be easier to find out where the actual time is spent.
