             Summary: Found a dns translate bug in C/C++ sdk
                 Key: TUBEMQ-354
                 URL: https://issues.apache.org/jira/browse/TUBEMQ-354
             Project: Apache TubeMQ
          Issue Type: Bug
            Reporter: Guocheng Zhang

like below code:

If the updMasterAddrByDns() is called concurrently, it is likely to be overwritten. The function should only set the content of this translation, not in the overwrite mode.
