Date Tue, 12 Jan 2016 13:05:39 GMT

Benjamin Bannier commented on MESOS-4339:
-----------------------------------------

> The intention of this ticket is enable Framework sorted by weights, ...

Currently that sorting is supported.

I suggest to postpone changes here until we actually know how e.g., multiple roles might look
like (likely some time after MESOS-4284 delivers).

> Current framework sorter doesn't take into account of weights when sorting framework
belonging to a particular role, i.e., all frameworks has equal weights as 1. Considering the
role weight is controlled by the operator, enable the framework weight does not impact the
role level allocation decision from any greedy frameworks, but it will be beneficial to some
framework who could get more resources within a specific role.
> The framework weight will come from message FrameworkInfo when it got registered, and
FrameworkSorters will "add" framework with weight,
> this will eventually result a weighted framework sorting flow when master make the finally
allocation decision.
> Please review this ticket which I will work on if it's considered acceptable.
> Thanks a lot.
