      Description

      The example given for the user limit tunable doesn't actually show how that value comes into play. With 4 users, the Max() is 25 for both the user limit and the capacity limit (from my reading of the source). Either pushing the example to 5 users or raising the user limit to something higher than 25 would help a great deal. Also, presenting this info in tabular format showing how the max() value is in play would also be great.

        No one looks at Hadoop's documentation so this won't get fixed.
