> HDFS-6606 provided an optimized way of HDFS data transfer encryption. The optimized encryption
is build on top of SASL wrap/unwrap when auth-conf is configured.
> When user specifies auth-conf, he wants both integrity and confidential. While the current
implementation of the optimization implements only confidential with AES/CTR and there is
no integrity grantees, which means the implications of auth-conf were not strictly followed.
