[jira] [Created] (MESOS-9975) Sorter may leak clients.

Meng Zhu created MESOS-9975:
-------------------------------

             Summary: 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


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.
