Hudson commented on MAPREDUCE-3329:
-----------------------------------

Integrated in Hadoop-Hdfs-trunk #872 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/872/])
    MAPREDUCE-3329. Fixed CapacityScheduler to ensure maximum-capacity cannot be lesser than capacity for any queue.

> When configuring the capacity scheduler capacity and maximum-capacity, it allows the maximum-capacity to be less then the capacity.  I did not test to see what true limit is, I assume maximum capacity.
> output from mapred queue -list where capacity = 10%, max capacity = 5%.
> Queue Name : test2 
> Queue State : running 
> Scheduling Info : queueName: "test2", capacity: 0.1, maximumCapacity: 5.0, currentCapacity: 0.0, state: Q_RUNNING,
