> Flink needs documentation for network access control
> ----------------------------------------------------
>
> Key: FLINK-8311
> URL: https://issues.apache.org/jira/browse/FLINK-8311
> Project: Flink
> Issue Type: Improvement
> Components: Documentation, Runtime / Network
> Affects Versions: 1.4.0
> Reporter: Elias Levy
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
>
> There is a need for better documentation on what connects to what over which
> ports in a Flink cluster to allow users to configure network access control
> rules.
> E.g. I was under the impression that in a ZK HA configuration the Job
> Managers were essentially independent and only coordinated via ZK. But
> starting multiple JMs in HA with the JM RPC port blocked between JMs shows
> that the second JM's Akka subsystem is trying to connect to the leading JM:
> {code}
> INFO akka.remote.transport.ProtocolStateActor - No
> response from remote for outbound association. Associate timed out after
> [20000 ms].
> WARN akka.remote.ReliableDeliverySupervisor -
> Association with remote system [akka.tcp://[email protected]:6123] has
> failed, address is now gated for [5000] ms. Reason: [Association failed with
> [akka.tcp://[email protected]:6123]] Caused by: [No response from remote
> for outbound association. Associate timed out after [20000 ms].]
> WARN akka.remote.transport.netty.NettyTransport - Remote
> connection to [null] failed with
> org.apache.flink.shaded.akka.org.jboss.netty.channel.ConnectTimeoutException:
> connection timed out: /10.210.210.127:6123
> {code}
