Cannot upgrade Cassandra from 3.11.6 to 3.11.7

[farhan5900]

What happened: While upgrading Cassandra from 3.11.6 to 3.11.7, the upgrade failed with the following error message, despite being parameter passed for NUM_TOKENS:

Error: failed to update instance for new operatorversion default/cassandra-3.11.7-1.0.3: admission webhook "instance-admission.kudo.dev" denied the request: failed to check immutable parameters for Instance default/cassandra-instance: parameter 'NUM_TOKENS' was changed to immutable in operator version cassandra-3.11.7-1.0.3 but no value was provided

What you expected to happen: Successful upgrade from Cassandra 3.11.6 to 3.11.7

How to reproduce it (as minimally and precisely as possible):

• Install Cassandra operator version 3.11.6

  kubectl kudo install cassandra --app-version 3.11.6

• Once the operator is up and running, trigger an upgrade to 3.11.7

  kubectl kudo upgrade cassandra --instance cassandra-instance --app-version 3.11.7

  OR

  kubectl kudo upgrade cassandra --instance cassandra-instance --app-version 3.11.7 -p NUM_TOKENS=256

Anything else we need to know?: No

Environment:

• Kubernetes version (use kubectl version): v1.20.2
• Kudo version (use kubectl kudo version): v0.18.2
• Operator: cassandra
• operatorVersion: 3.11.6-1.0.1, 3.11.7-1.0.2+
• Cloud provider or hardware configuration: aws
• OS (e.g. from /etc/os-release): ubuntu
• Kernel (e.g. uname -a): 5.4.0-62-generic
• Install tools:
• Others:

@farhan5900 Can you recheck the scenario? I just tested this locally and it worked as expected:

aneumanns-MBP:kudo-cassandra-operator aneumann$ kubectl-kudo upgrade cassandra --instance cassandra-instance --app-version 3.11.7
operatorversion default/cassandra-3.11.7-1.0.2 created
Error: failed to update instance for new operatorversion default/cassandra-3.11.7-1.0.2: admission webhook "instance-admission.kudo.dev" denied the request: failed to check immutable parameters for Instance default/cassandra-instance: parameter 'NUM_TOKENS' was changed to immutable in operator version cassandra-3.11.7-1.0.2 but no value was provided
aneumanns-MBP:kudo-cassandra-operator aneumann$ kubectl-kudo upgrade cassandra --instance cassandra-instance --app-version 3.11.7 -p NUM_TOKENS=256
operatorversion default/cassandra-3.11.7-1.0.2 already installed
instance default/cassandra-instance updated
aneumanns-MBP:kudo-cassandra-operator aneumann$

Thanks, @ANeumann82 for checking. I also checked again, It is working fine now.
