Subject [jira] [Commented] (YARN-6363) Extending SLS: Synthetic Load Generator
Date Fri, 31 Mar 2017 18:03:41 GMT

    [ https://issues.apache.org/jira/browse/YARN-6363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15951406#comment-15951406

Wangda Tan commented on YARN-6363:
----------------------------------

[~curino], thanks for adding this feature, it will be very helpful and convenient to run tests
under generated cases. I was thinking about how to model a probability distribution of generated
workload before, and it looks your patch addresses the problem :).

Since this patch need rebase, I haven't run tests yet.

Some comments/questions to the impl:

1) AMSimulator
- submitReservation => submitReservationWhenSpecified

2) Why changes to CapacitySchedulerQueueManager needed? Is it possible to do it in SLS? 

3) ENABLE_RESERVATION_SYSTEM, should we just take configs in yarn-site? 

4) For the syn.json, does it support non-reservation workload?
