Subject [jira] [Commented] (MESOS-6247) Enable Framework to set weight
Date Wed, 05 Oct 2016 00:11:20 GMT

    [ https://issues.apache.org/jira/browse/MESOS-6247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15547134#comment-15547134

Benjamin Mahler commented on MESOS-6247:
----------------------------------------

Setting weight for a framework means that the FrameworkID acts a sub-role. This would be a
hacky implementation of hierarchical roles:

{noformat}
                    ^
                  /   \
           BigData     Services
              ^
            /   \
FrameworkId1     FrameworkId2
{noformat}

This approach only supports 2 levels of roles and the leaf nodes are not roles, they are framework
ids (which act as a special kind of role). We should support hierarchical roles directly,
supporting more than just 2 levels and having roles as the only allocation entity:

{noformat}
                    ^
                  /   \
           BigData     Services
              ^
            /   \
       Spark     YARN
{noformat}

> We'd like to enable framework's weight when it register. So the framework can share resources
based on weight within the same role.
