It's not totally clear what the first part of this error message means.
How about changing the message to:
```
logWarning(s"A job was submitted with scheduler pool $poolName, which has
not been configured." +
"This can happen when the file that pools are read from isn't set, or
when that file " +
s"doesn't contain $poolName. Created $poolName with default
configuration (" +
s"schedulingMode: $DEFAULT_SCHEDULING_MODE, minShare:
$DEFAULT_MINIMUM_SHARE, " +
s"weight: $DEFAULT_WEIGHT)")
```
