Klaus Ma commented on MESOS-5600:
---------------------------------
Think more about that, current behaiour is right: if total is updated, it will
re-calculate all, otherwise, only related client is updated.when update weight,
we should do the same thing.
> "dirty" was never set back as false in sorter

> dirty was set as true when the total resource was updated in the cluster, but
> it was never set back as false. The dirty should be set back as false in
> DRFSorter::sort
> https://github.com/apache/mesos/blob/master/src/master/allocator/sorter/drf/sorter.cpp#L320-L334
> The reason that we cannot detect this is because once an agent was added to
> cluster, the dirty will be set as true and the sorter will always call sort()
> to calculate share for each framework, this will impact the performance.
