Subject [jira] [Created] (YARN-4022) queue not remove from webpage(/cluster/scheduler) when delete queue in xxx-scheduler.xml
Date Thu, 06 Aug 2015 09:52:04 GMT
forrestchen created YARN-4022:
---------------------------------

             Summary: queue not remove from webpage(/cluster/scheduler) when delete queue
in xxx-scheduler.xml
                 Key: YARN-4022
                 URL: https://issues.apache.org/jira/browse/YARN-4022
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
            Reporter: forrestchen


When I delete an existing queue by modify the xxx-schedule.xml, I can still see the queue
information block in webpage(/cluster/scheduler) though the 'Min Resources' items all become
to zero and have no item of 'Max Running Applications'.
I can still submit an application to the deleted queue and the application will run using
'root.default' queue instead, but submit to an un-exist queue will cause an exception.

My expectation is the deleted queue will not displayed in webpage and submit application to
the deleted queue will act just like the queue doesn't exist.

PS: There's no application running in the queue I delete.

Some related config in yarn-site.xml:

{code}
<property>
        <name>yarn.scheduler.fair.user-as-default-queue</name>
        <value>false</value>
</property>

<property>
        <name>yarn.scheduler.fair.allow-undeclared-pools</name>
        <value>false</value>
</property>
{code}
