--------------------------------
Thanks [~templedf]. -1.0f is the value to disable the {{maxAMShare}} introduced
in YARN-2187.
> FairScheduler should log information about AM-resource-usage and max-AM-share

> There are several cases where jobs in a queue or stuck likely because of
> maxAMShare. It is hard to debug these issues without any information.

> queues.
