Queues in hadoop 2.0.4

[Pedro Sá da Costa <ps...@gmail.com>]

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=$QUEUE_NAME;)?

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
