Chang Li commented on YARN-2556:
--------------------------------

[~sjlee0] Thanks so much for patiently guiding me to improve the work! I have updated my patch
according to your suggestions and create a JobHistoryFileReplayHelper to extract those common
code between v1 and v2 JobHistoryFileReplay mappers. Please let me know what you think of
the latest patch. Thanks!

> 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.
