>
> In case of multi-master Kudu cluster, the C++ client fails to re-acquire 
> authn token in the following scenario:
> # Client is running against a multi-master cluster.
> # Client successfully authenticates and gets an authn token by calling 
> ConnectToCluster.
> # Client keeps the connection to leader master open, but follower masters 
> close connections to the client due to inactivity.
> # After the authn token expires, a change in the master leadership happens.
> # Client tries to open a table, first making a request to the former leader 
> master.  However, the former leader returns NOT_THE_LEADER error.
> Eventually, the latter operation fails out with the following error:
> {{Timed out: GetTableSchema timed out after deadline expired}}
> In the case of that error, along with the message above, the client is also 
> logging messages like:
> {{Unable to determine the new leader Master: Not authorized: Client 
> connection negotiation failed: client connection to IP:port: 
> FATAL_INVALID_AUTHENTICATION_TOKEN: Not authorized: authentication token 
> expired}}
