Subject Re: Queues in hadoop 2.0.4
Date Thu, 30 May 2013 13:13:20 GMT
The Resourcemanager manages the queues in hadoop 2.0.4.  As far as the specifics it depends
on the scheduler you use.  If you use the capacity scheduler or fair scheduler you can have
multiple queues.  Take a look at the documentation here for capacity scheduler: http://hadoop.apache.org/docs/r2.0.4-alpha/hadoop-yarn/hadoop-yarn-site/CapacityScheduler.html

Any example capacity-scheduler.xml config file is here: http://svn.apache.org/viewvc/hadoop/common/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/conf/capacity-scheduler.xml?revision=1432931&view=markup

Subject: Queues in hadoop 2.0.4

I am using hadoop 2.0.4

1 - Which component manage queues? Is it the jobtracker?

2 - If so, it is possible to define several queues (set mapred.job.queue.name<http://mapred.job.queue.name>=$QUEUE_NAME;)?

Best regards,
