Subject [jira] [Commented] (MESOS-703) master fails to respect updated FrameworkInfo when the framework scheduler restarts
Date Wed, 25 Sep 2013 18:56:07 GMT

    [ https://issues.apache.org/jira/browse/MESOS-703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13777916#comment-13777916
] 

Vinod Kone commented on MESOS-703:
----------------------------------

Updating FrameworkInfo is a feature that is not cleanly supported yet. We have plans to get
to it before we release 1.0. 

That said, the only current way to update FrameworkInfo is to restart the master and the slaves
*after* you restart the framework with updated FrameworkInfo.

> When I first ran marathon it was running as a personal user and registered with mesos-master
as such due to putting an empty string in the user field. When I restarted marathon as "nobody",
tasks were still being run as the personal user which didn't exist on the slaves. I know marathon
was trying to send a FrameworkInfo with nobody listed as the user because I hard coded it
in. The tasks wouldn't run as "nobody" until I restarted the mesos-master. Each time I restarted
the marathon framework, it reregistered with mesos-master and mesos-master wrote to the logs
that it detected a failover because the scheduler went away and then came back.
> I understand the scheduler failover, but shouldn't mesos-master respect an updated FrameworkInfo
when the scheduler re-registers?
