You are absolutely right, thanks for catching this!
> Perform mutual authentication during SSL handshakes
> ---------------------------------------------------

> Key: FLINK-9312
> URL: https://issues.apache.org/jira/browse/FLINK-9312
> Project: Flink
> Issue Type: New Feature
> Components: Security
> Reporter: Stephan Ewen
> Priority: Major
> Fix For: 1.6.0
>
>
> 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.
