Yong Qiao Wang commented on MESOS-3177: --------------------------------------- [~adam-mesos], can you help review the related patches with REVIEWABLE status? Thanks! > Dynamic roles/weights configuration at runtime > ---------------------------------------------- > > Key: MESOS-3177 > URL: https://issues.apache.org/jira/browse/MESOS-3177 > Project: Mesos > Issue Type: Epic > Components: master, slave > Reporter: Cody Maloney > Assignee: Yong Qiao Wang > Labels: mesosphere > > All roles and weights must currently be specified up-front when starting > Mesos masters currently. In addition, they should be consistent on every > master, otherwise unexpected behavior could occur (You can have them be > inconsistent for some upgrade paths / changing the set). > This makes it hard to introduce new groups of machines under new roles > dynamically (Have to generate a new master configuration, deploy that, before > we can connect slaves with a new role to the cluster). > Ideally an administrator can manually add / remove / edit roles and have the > settings replicated / passed to all masters in the cluster by Mesos. > Effectively Mesos takes ownership of the setting, rather than requiring it to > be done externally. > In addition, if a new slave joins the cluster with an unexpected / new role > that should just work, making it much easier to introduce machines with new > roles. (Policy around whether or not a slave can cause creation of a new > role, a given slave can register with a given role, etc. is out of scope, and > would be controls in the general registration process). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
