Dear Team, Has anyone experienced this issue as I am also experiencing the similar issue with 3 node clusters in isolated mode, even though the StandardAuthorizer is enabled its still giving this error.
appuser@kafka01 secrets]$ kafka-acls --bootstrap-server broker01.abc.net:9094 --command-config rw-sa.properties --add --allow-principal User:rw-sa --operation Read --operation Write --topic '*' Adding ACLs for resource `ResourcePattern(resourceType=TOPIC, name=*, patternType=LITERAL)`: (principal=User:rw-sa, host=*, operation=WRITE, permissionType=ALLOW) (principal=User:rw-sa, host=*, operation=READ, permissionType=ALLOW) Error while executing ACL command: org.apache.kafka.common.errors.SecurityDisabledException: No Authorizer is configured. java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.SecurityDisabledException: No Authorizer is configured. at java.base/java.util.concurrent.CompletableFuture.reportGet(CompletableFuture.java:396) at java.base/java.util.concurrent.CompletableFuture.get(CompletableFuture.java:2073) at org.apache.kafka.common.internals.KafkaFutureImpl.get(KafkaFutureImpl.java:165) at kafka.admin.AclCommand$AdminClientService.$anonfun$addAcls$3(AclCommand.scala:115) at scala.collection.IterableOnceOps.foreach(IterableOnce.scala:576) at scala.collection.IterableOnceOps.foreach$(IterableOnce.scala:574) at scala.collection.AbstractIterable.foreach(Iterable.scala:933) at scala.collection.IterableOps$WithFilter.foreach(Iterable.scala:903) at kafka.admin.AclCommand$AdminClientService.$anonfun$addAcls$1(AclCommand.scala:112) at kafka.admin.AclCommand$AdminClientService.addAcls(AclCommand.scala:111) at kafka.admin.AclCommand$.main(AclCommand.scala:73) at kafka.admin.AclCommand.main(AclCommand.scala) Caused by: org.apache.kafka.common.errors.SecurityDisabledException: No Authorizer is configured. However listing ACL shows okay without any errors. [appuser@kafka01 secrets]$ kafka-acls --bootstrap-server broker01.abc.net:9094 --command-config adminclient.properties --list There is a similar issue but I couldn't understand the resolution Fix. https://lists.apache.org/thread/tx4s71ycm23h9n8z3o8pfwfd45d5jrfw
