Subject [jira] [Commented] (YARN-3047) [Data Serving] Set up ATS reader with basic request serving structure and lifecycle
Date Fri, 27 Mar 2015 18:17:54 GMT

    [ https://issues.apache.org/jira/browse/YARN-3047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14384285#comment-14384285
] 

Sangjin Lee commented on YARN-3047:
-----------------------------------

Took a quick look at the latest patch (v06). Looks good for the most part, but Field.java
and TestTimelineReaderServer.java are missing the license. Could you please fix that quickly?
The patch applies cleanly for me BTW.

bq. And I think max number of HttpServer threads should not be merely 10. Filed YARN-3407
for it

If I'm not mistaken, it looks like the number of threads can be controlled by HTTP_MAX_THREADS?
And also by default jetty maxes out at 250? Wouldn't that be enough?

> Per design in YARN-2938, set up the ATS reader as a service and implement the basic structure
as a service. It includes lifecycle management, request serving, and so on.
