Hadoop RPC protection

[ Edited ]

Hello Team,


We have CDH 5.13 with kerberos and TLS Enabled Cluster.


By default Cloudera set the below property to Authentication.  Authentication


My question is


1. I have TLS Enabled Cluster, Do i have to update property to  Privacy  

Data Transfer Encryption Algorithm  AES 256

Enable Data Transfer Encryption      Yes


2. What if i have updated only below property and not above mentioned rest 2? to  Privacy 


3. If i have set to authentication, does that means data Transfer in between Datanodes and in between datanodes to client will not be ecnrypted?


Kindly suggest for above 3 queries.
