Subject [jira] [Commented] (MAPREDUCE-6546) reconcile the two versions of the timeline service performance tests

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

Thanks [~sjlee0] for the latest patch few more nits :
# Its better to capture the defaults for {{timeline service version}} and {{-mtype}}
# {{\[-d <path>\] root path of job history files}} => {{\[-d <path>\] hdfs
root path of job history fileS}}
# I had configured for V2(ATS) and when submitting a job missed to specify {{-v}} option,
job succeeded with counter stats as 
{code}
	org.apache.hadoop.mapreduce.TimelineServicePerformance$PerfCounters
		TIMELINE_SERVICE_WRITE_COUNTER=100
		TIMELINE_SERVICE_WRITE_FAILURES=100
		TIMELINE_SERVICE_WRITE_KBS=100
		TIMELINE_SERVICE_WRITE_TIME=13
	File Input Format Counters 
		Bytes Read=0
	File Output Format Counters 
		Bytes Written=0
TRANSACTION RATE (per mapper): 7692.307692307692 ops/s
IO RATE (per mapper): 7692.307692307692 KB/s
TRANSACTION RATE (total): 7692.307692307692 ops/s
IO RATE (total): 7692.307692307692 KB/s
{code}
So wondering whether we can add a check to confirm \#failures is != write counters before
declaring it as success when {{-mtype}} option is 1 ?

Apart from this ran it for all V2 options and its running fine.

> 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.
