Description
Credit to qwertymaniac who reported this.
The change made by
HDFS-10320now 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.
