> FairScheduler: totalMaxShare is not calculated correctly in
> computeSharesInternal for some cases.
> If the sum of MAX share of all Schedulables is more than Integer.MAX_VALUE
> ,but each individual MAX share is not equal to Integer.MAX_VALUE. then
> totalMaxShare will be a negative value, which will cause all fairShare are
> wrongly calculated.
