    Description

      Credit to qwertymaniac who reported this.

      The change made by HDFS-10320 now causes all 1-rack cluster to keep printing below:
      WARN org.apache.hadoop.net.NetworkTopology
      Failed to find datanode (scope="" excludedScope="/default").

      This was added in HDFS-10320 to replace an exception that caused NN terminate. A warn log was added. But thinking closely, this should be debug to reduce confusion.
