Todd Lipcon commented on MAPREDUCE-2836:
----------------------------------------
Two tiny nits:
- the indentation is still off on the declaration of {{allowUndeclaredPools}}
- for JUnit 4, assertions come from the org.junit.Assert package - you can do:
{code}
import static org.junit.Assert.*;
{code}
in order to get all of them imported
Otherwise looks great!
> Provide option to fail jobs when submitted to non-existent pools.

> In some environments, it might be desirable to explicitly specify the fair
> scheduler pools and to explicitly fail jobs that are not submitted to any of
> the pools.
> Current behavior of the fair scheduler is to submit jobs to a default pool if
> a pool name isn't specified or to create a pool with the new name if the pool
> name doesn't already exist. There should be a configuration option for the
> fair scheduler that causes it to noisily fail the job if it's submitted to a
> pool that isn't pre-specified or if the specified pool doesn't exist.
