      Description

      The fair scheduler can run jobs in a single pool (queue) in FIFO or fair share mode. In FIFO mode one job runs at a time, in priority order, while in fair share mode multiple jobs can run at the same time, and they share the capacity of the pool. This JIRA is to add the latter feature to Capacity Scheduler as an option - the default would remain FIFO.
