tensorflow.python.framework.errors_impl.InternalError: HadoopFileSystem is not initialized correctly

Start at io_wrapper.GetLogdirSubdirectories and the tf.io.gfile.exists call shown in the traceback, then investigate why HadoopFileSystem is not initialized for hdfs://tensorboard_log. Reproduce with the reported TensorBoard 2.11.2 setup; done means an HDFS log directory can be loaded without the InternalError.
