> proposed fix: https://github.com/apache/mesos/pull/248
> I observed this in my environment, where I had two frameworks that used the same ExecutorID and then triggered a master failover. The master refuses to reregister the slave because it's not considering the owning-framework of the ExecutorID when computing ExecutorID uniqueness, and concludes (incorrectly) that there's an erroneous duplicate executor ID:

> {code}
> (yes, "default" is probably a terrible name for an ExecutorID - that's a separate discussion!)
