Re: Question about akka configuration for FLIP-6


Hi Gray,

Thanks for your useful information! Here I wonder if the following configs still valid on FLIP-6 mode.

1. akka.transport.heartbeat.interval
2. akka.transport.heartbeat.pause

It seems they are different from HeartbeatServices and possibly still valid.

Best,
tison.

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 [1].

Hi Tony,

You are right that with FLIP-6 Akka is abstracted away. If you want custom
heartbeat settings, you can configure the options below [1]:

    heatbeat.interval
    heartbeat.timeout

The config option taskmanager.exit-on-fatal-akka-error is also not relevant
anymore. I closest I can think of is taskmanager.registration.timeout [2].

Best,
Gary

Hi,

I'm going to migrate my flink cluster from 1.4.0 to 1.5.3, and I have been trying to map config file
to the latest version. I used to use these three configuration. Are they still needed in FLIP-6 mode?
Moreover, is any akka config still needed in FLIP-6 mode? Since I had a impression that FLIP-6
tried to get rid of akka and use its own rpc interface. Please correct me if I misunderstood. Thanks.

akka.watch.heartbeat.interval
akka.watch.heartbeat.pause
taskmanager.exit-on-fatal-akka-error
