--------------------------------

             Summary: The caller program will be shut down directly when the execution of Kafka script is abnormal
                 Key: KAFKA-13398
                 URL: https://issues.apache.org/jira/browse/KAFKA-13398
             Project: Kafka
          Issue Type: Improvement
          Components: admin
    Affects Versions: 3.0.0
            Reporter: RivenSun


hello [~showuon] and [~guozhang]

 
Kafka has many key functions that have not yet been integrated into AdminClient, so I have to use some Scala classes in the Kafka Server package in my java program, such as: `ReassignPartitionsCommand`, `ConsumerGroupCommand` (in order to reset group offsets), etc., to call their main Methods to achieve specific functions.

Problem: In different Kafka versions, these Scala classes may have different requirements for input parameters, or they may have different treatments for the results of command execution.
1) ReassignPartitionsCommand requires `--bootstrap-server` is required in the latest high version, but requires `--zookeeper` in the low version.
Once the parameter verification fails, the Exit.exit(1, Some(message)) method will be called, which will cause my process to shut down directly.
2) In Kafka 3.0.0 version, there is this code at the end in the main method of `ReassignPartitionsCommand`
{code:java}
// If the command failed, exit with a non-zero exit code.
 if (failed) {
 Exit.exit(1)
 }{code}

This will also make my process shut down directly

So I hope that the Kafka community will be able to print out the reason and stack of the corresponding exception when the parameter verification fails or the execution command is abnormal, and then return from the main method of the command, but don't call `Exit.exit(...)` method. Of course, when the script is executed on the machine, there is no problem with exiting directly.

2. At present, it seems that only scripts can be used to add/update/delete SCRAM credentials for users, eg:
{code:java}
> bin/kafka-configs.sh --zookeeper localhost:2182 --zk-tls-config-file zk_tls_config.properties --alter --add-config'SCRAM-SHA-256=[iterations=8192,password=alice- secret],SCRAM-SHA-512=[password=alice-secret]' --entity-type users --entity-name alice{code}
In Kafka 3.0.0 version, the alterUserScramCredentials method in KafkaAdminClient does not support calling yet, and the AltUserScramCredentialsOptions parameter is modified by the annotation @InterfaceStability.Evolving. So I currently have to use `ConfigCommand` to achieve this function, but `ConfigCommand` also has the same logic: Exit.exit( ...).
