-------------------------------
Summary: Avoid hierarchical shuffling in the random sorter.
Key: MESOS-9724
URL: https://issues.apache.org/jira/browse/MESOS-9724
Project: Mesos
Issue Type: Improvement
Reporter: Meng Zhu
Assignee: Meng Zhu
Due to the presence of hierarchical weights, the random sorter currently
shuffles level-by-level. We should be able to shuffle all the active leaves
only once by calculating (and caching) active leaves' relative weights. This
should improve the performance in the presence of hierarchical roles.
