[jira] [Commented] (MESOS-1763) Add support for multiple roles to be specified in FrameworkInfo

["Christopher Hunt (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-1763?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15401441#comment-15401441 ] 

Christopher Hunt commented on MESOS-1763:
-----------------------------------------

I'd like to add that the requirement for a framework to register interest in multiple roles is important. Given a standard DC/OS setup, there's a "slave_public" role associated with a few slaves and the remainder are "*" to represent private slaves. Therefore in DC/OS, a framework can only presently partake in two roles; public and private. We have use-cases where we would like to further assign private slaves to other tasks. For example, some might run Spark jobs, some Kafka and others our own framework's microservices.

By way of solution, I'd suggest that the RequestResources call be leveraged for frameworks to register their resource and role requirements.

> Currently frameworks have the ability to set only one (resource) role in FrameworkInfo. It would be nice to let frameworks specify multiple roles so that they can do more fine grained resource accounting per role.
