Subject [jira] [Commented] (YARN-1414) with Fair Scheduler reserved MB in WebUI is leaking when killing waiting jobs
Date Wed, 05 Feb 2014 23:18:09 GMT

    [ https://issues.apache.org/jira/browse/YARN-1414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13892738#comment-13892738

Sandy Ryza commented on YARN-1414:
----------------------------------

bq. After it updates the root queue, it will then update the child queue.
Where are you seeing that happen?  From what I can tell, children update their parents, but
not the other way around:

{code}
  public void unreserveResource(String user, Resource res) {
    reservedContainers.decr();
    reservedMB.decr(res.getMemory());
    reservedVCores.decr(res.getVirtualCores());
    QueueMetrics userMetrics = getUserMetrics(user);
    if (userMetrics != null) {
      userMetrics.unreserveResource(user, res);
    }
    if (parent != null) {
      parent.unreserveResource(user, res);
    }
  }
{code}
