     [ https://issues.apache.org/jira/browse/TUBEMQ-354?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Guocheng Zhang updated TUBEMQ-354:
----------------------------------
    Description: 
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.

https://github.com/apache/incubator-tubemq/blob/master/tubemq-client-twins/tubemq-client-cpp/src/client_service.cc#L278

And all dns translation operations should be performed under dns_mutex_ instead of mutex_
