Flink - multiple job managers in jobmanager.rpc.address

I'm trying to configure Flink with two job managers for HA. Should I specify both of them in flink-conf.yaml / jobmanager.rpc.address ? If yes how?

Solution

  • You don't need to. In HA mode the rpc.address is chosen automatically by default. Have a look at docs.

    By default, the job manager will pick a random port for inter process communication. You can change this via the high-availability.jobmanager.port key. This key accepts single ports (e.g. 50010), ranges (50000-50025), or a combination of both (50010,50011,50020-50025,50050-50075).
