HDFS considers blocks under-replicated if topology script is configured with only 1 rack

      Description

      HDFS treats the mere presence of a topology script being configured as evidence that there are multiple racks. If there is in fact only a single rack, the NN will try to place the blocks on at least two racks, and thus blocks will be considered to be under-replicated.
