Yan Xu created MESOS-7186:
-----------------------------
Summary: Metrics about used/allocated shared resources are
incorrect accounted.
Key: MESOS-7186
URL: https://issues.apache.org/jira/browse/MESOS-7186
Project: Mesos
Issue Type: Bug
Reporter: Yan Xu
Certain gauges like {{master/<resource>_used}} are calculated from data
structures like {{hashmap<FrameworkID, Resources> usedResources}} which are
keyed off by the framework. However because frameworks under the same role can
have the same shared persistent volumes, we need to de-duplicate (via Resource
arithmetics) before extracting and summing up the double scalar values.
