Matei Zaharia commented on MAPREDUCE-707:
-----------------------------------------
I should also add that my original intent in the JIRA was to have a separate
way of setting the pool that doesn't require using the
mapred.fairscheduler.poolnameproperty. This way, users could set
poolnameproperty to something else (e.g. group.name for a Unix group). However,
I think it's overkill to add a second way of setting the pool name, so I'd be
okay with just a patch to mapred-default.xml if that works.

> 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.
