-----------------------------------------
Hi Alan,
If you just want to get this behaviour as a fair scheduler user, the properties
can be set in your mapred-site.xml. If you want to submit a patch so that this
behaviour is the default, you have to edit mapred-default.xml, which is
available in src or perhaps src/java in the mapreduce project.
> Provide a jobconf property for explicitly assigning a job to a pool

> Key: MAPREDUCE-707
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-707
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Components: contrib/fair-share
> Reporter: Matei Zaharia
> Priority: Trivial
>
> A common use case of the fair scheduler is to have one pool per user, but
> then to define some special pools for various production jobs, import jobs,
> etc. Therefore, it would be nice if jobs went by default to the pool of the
> user who submitted them, but there was a setting to explicitly place a job in
> another pool. Today, this can be achieved through a sort of trick in the
> JobConf:
> {code}
> <property>
> <name>mapred.fairscheduler.poolnameproperty</name>
> <value>pool.name</value>
> </property>
> <property>
> <name>pool.name</name>
> <value>${user.name}</value>
> </property>
> {code}
> This JIRA proposes to add a property called mapred.fairscheduler.pool that
> allows a job to be placed directly into a pool, avoiding the need for this
> trick.
