If you use the Java Client the logging should be quite easy. You can add
the SLF4J simple logger to your dependencies:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.22</version>
</dependency>
And set the system property org.slf4j.simpleLogger.defaultLogLevel to the
log level you want - info, debug etc. This should print the logs to the
standard output.
You can also try if the problem is in the Kerberos configuration by
changing the protocol map from SASL_PLAINTEXT to PLAINTEXT:
listener.security.protocol.map=SSL:SSL,REPLICATION:PLAINTEXT
in the configuration I suggested above.
