Subject [jira] [Commented] (YARN-2556) Tool to measure the performance of the timeline server
Date Mon, 22 Sep 2014 09:06:33 GMT

    [ https://issues.apache.org/jira/browse/YARN-2556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14143039#comment-14143039

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).

> 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.
