> Encrypted shuffle is enabled in hadoop 2.6 which make the process of shuffle data safer.
This feature is necessary in spark. AES  is a specification for the encryption of electronic
data. There are 5 common modes in AES. CTR is one of the modes. We use two codec JceAesCtrCryptoCodec
and OpensslAesCtrCryptoCodec to enable spark encrypted shuffle which is also used in hadoop
encrypted shuffle. JceAesCtrypoCodec uses encrypted algorithms  jdk provides while OpensslAesCtrCryptoCodec
uses encrypted algorithms  openssl provides. 
> Because ugi credential info is used in the process of encrypted shuffle, we first enable
encrypted shuffle on spark-on-yarn framework.
