Examples of TServerInstance

org.apache.accumulo.server.master.state.TServerInstance
A tablet is assigned to a tablet server at the given address as long as it is alive and well. When the tablet server is restarted, the instance information it advertises will change. Therefore tablet assignments can be considered out-of-date if the tablet server instance information has been changed.
