----------------------------------
Summary: "dirty" was never set back as false in sorter
Key: MESOS-5600
URL: https://issues.apache.org/jira/browse/MESOS-5600
Project: Mesos
Issue Type: Bug
Reporter: Guangya Liu
Assignee: Guangya Liu
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.
