> Issue Type: Bug
> Components: master
> Affects Versions: 1.4.0, 1.5.0, 1.6.0, 1.7.0, 1.7.1
> Reporter: Alexey Serbin

> 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}}
