Naganarasimha G R commented on MAPREDUCE-6546:
----------------------------------------------

* {{TimelineServicePerformance.parseArgs}} after *if ("-v".equals(args[i]))* 
there has to be a else if not execution fails
* As the MR task was failing output is coming as NAN, May be we can check for 
the exit code or the job status and then print the job stats 
{code}
TRANSACTION RATE (per mapper): NaN ops/s
IO RATE (per mapper): NaN KB/s
TRANSACTION RATE (total): NaN ops/s
IO RATE (total): NaN KB/s
{code}

> reconcile the two versions of the timeline service performance tests

> The trunk now has a version of the timeline service performance test 
> (YARN-2556). The timeline service v.2 (YARN-2928) also has a performance 
> test, and these two versions are quite similar (by design).
> We need to reconcile the two.
