Zhijie Shen commented on YARN-2556:

[~jeagles], it sounds an interesting work. Is it possible to see the throughput 
difference between TimelineDataManager and the web front interface? I suspect 
the web front interface is going to be bottleneck to throttle the end-to-end 
performance. With this analysis, we can have clearer picture about the 
reasonable to timeline server instances required to get rid of web font 
interface bottleneck (YARN-2520).

>            Reporter: Jonathan Eagles
>            Assignee: chang li
> We need to be able to understand the capacity model for the timeline server 
> to give users the tools they need to deploy a timeline server with the 
> correct capacity.
> I propose we create a mapreduce job that can measure timeline server write 
> and read performance. Transactions per second, I/O for both read and write 
> would be a good start.
> This could be done as an example or test job that could be tied into gridmix.
