Matei Zaharia commented on MAPREDUCE-707:
-----------------------------------------

In other words, I want to treat PoolManager, PoolSchedulable, JobSchedulable, 
etc as data structures, and decide externally when updates need to happen and 
when they don't, so that all that control logic is in one or two places (the 
event handlers in the FairScheduler and the UI code in FairSchedulerServlet).

> Provide a jobconf property for explicitly assigning a job to a pool

> 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.
