When a collective controller is created and started, the following error is reported:

CWWKX8133E: The host name of the security identity of the server is different from the current host name. Identity host name: <ip-address>, current host name: <FQHN>. This discrepancy will cause certain collective operations to fail.

For example:

CWWKX8133E: The host name of the security identity of the server is different from the current host name. Identity host name: 98.124.199.21, current host name: node01.localdomain.com. This discrepancy will cause certain collective operations to fail.

The reason, this happens is because the collective controller was created with the command, and it tried to resolve the hostname, but it may depend on how well your test Linux environment is configured, especially if it is a lab environment, where less attention to naming conventions is common.

./collective create controller1 --keystorePassword=secureme

However, no hostname was specified, delete the collective configuration, and then re-create it using the following command:

./collective create controller1 --keystorePassword=secureme --hostname=node01.localdomain

Tip: Save the server.xml so you don’t have to re-configure the collective’s server.xml again
