> Encrypted shuffle is enabled in hadoop 2.6 which make the process of shuffle
> data safer. This feature is necessary in spark. We reuse hadoop encrypted
> shuffle feature to spark and because ugi credential info is necessary in
> encrypted shuffle, we first enable encrypted shuffle on spark-on-yarn
> framework.
