Description

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
