zjncs opened a new pull request, #11135: URL: https://github.com/apache/rocketmq/pull/11135
### Motivation `mqadmin exportMetadata` summed `retryQueueNums` of the same subscription group over every master of the cluster, the way topic queue numbers are totaled. But a subscription group config is cluster-wide: a group exported from an N-broker cluster came out with N times its real `retryQueueNums`, and re-importing that metadata inflated every group's retry queues. ### Modifications Keep the first seen config per group instead of summing, matching the cluster-wide semantics of subscription group config. ### Verification Fail-before (new test, run against the unpatched code): ``` ExportMetadataCommandTest#testSubscriptionGroupRetryQueueNumsNotAccumulatedAcrossBrokers java.lang.AssertionError: retryQueueNums must not be summed across the two masters expected:<1> but was:<2> ``` Pass-after: ``` Tests run: 1, Failures: 0, Errors: 0, Skipped: 0 -- ExportMetadataCommandTest ``` -- This is an automated message from the Apache Git Service.
