> 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.
