Hi Sichen Thanks for proposing this, this for sure a nice enhancement for SLS. For SLS improvements, feel free to create JIRA tickets under https://issues.apache.org/jira/browse/YARN-5065, that’s the umbrella we track all related items. For scheduling requests support, there is an existing JIRA and an existing patch in https://issues.apache.org/jira/browse/YARN-8007, would you like to take a look?

Add input support for the scheduling request format. Yes. I suppose this change is in SLS end (client to generate requests) 2. Add support for scheduling request resource format in NMSim. Makes sense. 3. Adding scheduling request support for the Capacity Scheduler(maybe it is already done in current version). This support is already there. Adding to this, major challenge is to specify constrains per app level and verifying results. I also suggest to cross check the scheduler invariants check support added as per YARN-6547 and see how we can incorporate same to predict o/p - Sunil On Mon, Aug 13, 2018 at 10:39 PM Yufei Gu <flyrain...@gmail.com<mailto:flyrain...@gmail.com>> wrote: +YANG WEIWEI<mailto:cheersy...@hotmail.com> Make sense to me from SLS perspective, but I am not familiar with Placement Constraints.
