I should add that in FLIP-6 mode we are not relying on Akka's DeathWatch but
because Flink's RPC framework uses Akka, you are still able to configure the
other Akka config options .

You are right that with FLIP-6 Akka is abstracted away. If you want custom
heartbeat settings, you can configure the options below :
The config option taskmanager.exit-on-fatal-akka-error is also not relevant
anymore. I closest I can think of is taskmanager.registration.timeout .

Since I had a impression that FLIP-6tried to get rid of akka and use its own rpc interface. Please correct me if I misunderstood.
