[jira] [Commented] (YARN-6378) Negative usedResources memory in CapacityScheduler

    [ https://issues.apache.org/jira/browse/YARN-6378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16073266#comment-16073266 ] 

Filipp Zhinkin commented on YARN-6378:
--------------------------------------

Seems like hadoop 2.6.0 has the same problem, at least I'm facing negative memory and vcores usage with capacity scheduler:

{code:xml}
<queue xsi:type="capacitySchedulerLeafQueueInfo">
        <capacity>19.0</capacity>
        <usedCapacity>-69.52686</usedCapacity>
        <maxCapacity>90.0</maxCapacity>
        <absoluteCapacity>19.0</absoluteCapacity>
        <absoluteMaxCapacity>90.0</absoluteMaxCapacity>
        <absoluteUsedCapacity>0.0</absoluteUsedCapacity>
        <numApplications>10</numApplications>
        <queueName>default</queueName>
        <state>RUNNING</state>
        <resourcesUsed>
           <memory>-152576</memory>
           <vCores>-41</vCores>
        </resourcesUsed>
        <hideReservationQueues>false</hideReservationQueues>
        <nodeLabels>*</nodeLabels>
        <allocatedContainers>24</allocatedContainers>
        <reservedContainers>0</reservedContainers>
        <pendingContainers>0</pendingContainers>
        <numActiveApplications>10</numActiveApplications>
        <numPendingApplications>0</numPendingApplications>
        <numContainers>-41</numContainers>
        <maxApplications>1900</maxApplications>
        <maxApplicationsPerUser>855</maxApplicationsPerUser>
        <maxActiveApplications>102</maxActiveApplications>
        <maxActiveApplicationsPerUser>10</maxActiveApplicationsPerUser>
        <userLimit>10</userLimit>
        ...
  </queue>

> Courtesy Thomas Nystrand, we found that on two of our clusters configured with the CapacityScheduler, usedResources occasionally becomes negative.
