Vinod Kone commented on MESOS-1216:
-----------------------------------
Yes. We will enforce it as part of
https://issues.apache.org/jira/browse/MESOS-1215. For backwards compatibility
this patch won't enforce it.
> Attributes comparator operator should allow multiple attributes of same name
> and type

> Project: Mesos
> Issue Type: Bug
> Reporter: Vinod Kone
> Fix For: 0.19.0

>
> The fact that we currently don't support SET type in Attribute means that
> operators might end up having multiple attributes (e.g., slave attributes)
> with the same name and type but different value.
> But the comparator operator for Attributes expects unique (name, type)
> Attributes. This results in slave recovery failure when comparing
> checkpointed attributes with those set via flags.
> https://issues.apache.org/jira/browse/MESOS-1215 adds SET support, but for
> backwards compatibility we should fix the comparator operator first.
