Not able to change the priority of job using fair scheduler

[Chunky Gupta <ch...@vizury.com>]

Hi,

I have enabled the fair scheduler and everything is set to default with
only few configuration changes. It is working fine and multiple users can
run queries simultaneously.
But I am not able to change the priority from " *http://<JobTracker
URL>/scheduler*" .
Priority column is coming as a simple test not with a drag down column.
Same thing with pool column. Which configuration I missed for this.

http://hadoop.apache.org/docs/r0.20.2/fair_scheduler.html

Above link doesn't say anything about this. Please help me.

Thanks,
Chunky.
