Meng Zhu reassigned MESOS-9975:
-------------------------------
Assignee: Meng Zhu
> Sorter may leak clients.
> ------------------------
>
> Key: MESOS-9975
> URL: https://issues.apache.org/jira/browse/MESOS-9975
> Project: Mesos
> Issue Type: Bug
> Components: allocation
> Reporter: Meng Zhu
> Assignee: Meng Zhu
> Priority: Major
> Labels: resource-management
>
> In MESOS-9015, we allowed resource quantities to change when updating an
> existing allocation. When the allocation is updated to empty, however, we
> forget to remove the client in the map in the `sorter::update()` if the
> `newAllocation` is `empty()`.
> https://github.com/apache/mesos/blob/master/src/master/allocator/mesos/sorter/drf/sorter.hpp#L382-L384
> The above case could happen, for example, when a CSI volume with a stale
> profile is destroyed, it would be better to convert it into an empty resource
> since the disk space is no longer available.
