Issue Evaluation

Category: bug | Status: Confirmed

The error The sub command topiclist -c -n 192.168.25.11:9876 not exist indicates the operator is invoking the mqadmin tool with an incorrect subcommand name.

Root Cause: In the TopicTransfer controller, the command construction uses topicListCmd which resolves to topiclist, but the correct mqadmin subcommand is likely topicList (case-sensitive) or topicClusterList. The operator's cons.AdminToolDir + command concatenation produces an invalid mqadmin invocation.

Impact: TopicTransfer CRD is non-functional — cannot migrate topics between clusters.

Severity: Medium — affects the topic transfer feature specifically.

Issue Evaluation

Category: bug | Status: Needs Info

The topiclist -c -n subcommand not found error suggests a version mismatch between the mqadmin tool and the broker. The -c flag for topicList may not be supported in your RocketMQ version.

Please provide:

• RocketMQ server version
• The exact mqadmin command and version used
• Whether mqadmin topicList -n <namesrv> (without -c) works
