> Currently all HDFS RPCs performed by NNs/DNs/clients can be optionally
> encrypted. However, actual data read or written between DNs and clients (or
> DNs to DNs) is sent in the clear. When processing sensitive data on a shared
> cluster, confidentiality of the data read/written from/to HDFS may be desired.
