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_
