Subject [jira] [Commented] (YARN-3378) a load test client that can replay a volume of history files
Date Fri, 20 Mar 2015 07:15:40 GMT

Naganarasimha G R commented on YARN-3378:

Hi [~gtCarrera9], I think you took me wrongly its not that i am against having this jira and
infact i feel this kind of test is very much important, as i faced similar issue with ATS
V1 and i was checking with Zhijie. My intent was about reuse, IIUC YARN-2256, they too have
MR task which takes arguments like number of mappers, number of bytes to send and the interval.
and they are using Timeline client(v1) to post the entities based on these input. So my view
was to take one more configuration here to take the ATS version to which to Entites needs
to be posted (and other conf information related ATSV2) and make use of the same code to publish
Data to ATS V2.  But if we are planning to have much more functionality then we might not
be able reuse...

> It might be good to create a load test client that can replay a large volume of history
files into the timeline service. One can envision running such a load test client as a mapreduce
job and generate a fair amount of load. It would be useful to spot check correctness, and
more importantly observe performance characteristic.
