Description

Currently, the Flink processes encrypted connections via SSL:

• Data exchange TM - TM
• RPC JM - TM
• Blob Service JM - TM

However, the server side always accepts any client to build up the connection, meaning the connections are not strongly authenticated.

Activating SSL mutual authentication solves that - only processes that have the same certificate can connect.
