I ran across the Apache Twill [1] project recently whose goal is to reduce the complexity of developing distributed applications that run on YARN. My first thought is that it might offer additional capabilities and/or simplify our current MaaS implementation.
Here are a list of features provided by Twill that I think might be useful for MaaS. - Service discovery - Elastic scaling - High Availability - Placement policies - Which rack/host should the model run on? - Security - Kerberos ticket refresh? Just wanted to float the thought in the community and see if anyone has experience with Twill. I need to do some more research myself. [1] http://twill.apache.org/
