> I tried to start the resource manager using the capacity scheduler with a particular
queues maximum-capacity set to -1 which is supposed to disable it according to the docs but
I got the following exception:
> java.lang.IllegalArgumentException: Illegal value  of maximumCapacity -0.01 used in call
to setMaxCapacity for queue foo
