Hazelcast tcp-ip configuration cluster: Unwanted IPs join the cluster even after cluster-name is specified

问题

I have two hazelcast configure yaml files:

hazelcast-cluster1.yml:

  hazelcast:
    cluster-name: cluster1
    network:
      join:
        multicast:
          enabled:false
        tip-ip:
          enabled: true
          member-list:
           machineA
           machineB

hazelcast-cluster2.yml:

  hazelcast:
    cluster-name: cluster2
    network:
      join:
        multicast:
          enabled:false
        tip-ip:
          enabled: true
          member-list:
           machineC
           machineD

What I wanted is machineA and machineB forms a cluster while machineC and machineD does a separate cluster. However, when I started machineC, it forms a cluster with machinaA and machineB even though I specified the cluster names differently. How can I prevent unwanted node from joining a cluster?

回答1:

You have some typos in your configurations:

tip-ip => tcp-ip
member-list: - addresses should start with -
indentation is wrong

So your configuration should look like:

hazelcast:
  cluster-name: cluster1
  network:
    join:
      multicast:
        enabled:false
      tcp-ip:
        enabled: true
        member-list:
        - machineA
        - machineB

This may solve your issue. If not, please share the logs from all your Hazelcast members (as recommended by Neil Stevenson)

The log you have added shows two lines of interest. Line 1

INFO [main] [machineC]:5701 [cluster2] [4.0.1]

and line 13

INFO [main] [machineC]:5702 [dev] [4.0.1] Backpressure is disabled

Here cluster2 and dev are the cluster names. The first is as you specified but the second is the default.

Your config file hazelcast-cluster1.yml isn't being used. This is why there is a devcluster on machineA, machineB and machineC.

Further back in the logs it should show if an attempt is made to load hazelcast-cluster1.yml which would indicate if it hasn't been found or is corrupt in someway.
