You can do the following method,
copy to clipboard datanode clusterID for your example, CID-8bf63244-0510-4db6-a949-8f74b50f2be9
and run following command under HADOOP_HOME/bin directory
./hdfs namenode -format -clusterId CID-8bf63244-0510-4db6-a949-8f74b50f2be9
then this code formatted the namenode with datanode cluster ids.
ou must do as follow :
rm -Rf /home/prassanna/usr/local/hadoop/yarn_data/hdfs/*
bin/hadoop namenode -format
I had the same problem until I found an answer in this web site.
