Subject Re: Data transfer encryption

​persist data into HDFS, so if you wish the data transfer to be encrypted,
use "dfs.encrypt.data.transfer" . This only encrypts the transfer. As
another option you can enable transparent server side encryption in HBase
0.98 and higher. This will encrypt data for persistence inside HBase before
any write or data transfer using HDFS. For more information see the
Security section of our online manual:
​ ​

​RegionServers and the Master send
administrative messages between themselves using RPC. Communication between
RegionServers and clients is also by way of RPC. RPC can be secured by
using Kerberos authentication in conjunction with auth-conf SASL privacy
settings. Set up Kerberos and then set "hbase.rpc.protection" to "privacy"
in the HBase site configuration

What do you mean by "SSE"
