Subject [jira] [Commented] (YARN-1403) Separate out configuration loading from QueueManager in the Fair Scheduler
Date Thu, 05 Dec 2013 01:21:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-1403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13839644#comment-13839644
] 

Alejandro Abdelnur commented on YARN-1403:
------------------------------------------

* FairScheduler.java
** Given that the AllocationFileLoaderService is a service, shouldn'd its lifecycle start/stop
be managed as other services? here reinitialize() is doing start and there is no stop. this
is a bit off, no?
* FairSchedulerQueueInfo.java
** in case of reload, the maxApps var here never gets updated, shouldn't the getMaxApplications()
method be as follows so the max is properly refreshed?

{code}
  public int getMaxApplications() {
    return scheduler.getAllocationConfiguration().getQueueMaxApps(queueName);
  }
{code}
