> The {{Hdfs AbstractFileSystem}} is overwriting the token service set by the {{DFSClient}}.  The service is not necessarily the correct one since {{DFSClient}} is responsible for the service.  Most importantly, this improper behavior is overwriting the HA logical service which indirectly renders {{FileContext}} incompatible with HA.
