While formatting namenode by executing the command " bin/hadoop namenode -format " i get this error:
hduser@ubuntu:~/hadoop/bin$ ./hadoop namenode -format
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.
Error : Could not find or load main class org.apache.hadoop.hdfs.server.namenode.NameNode
matesio :
try removing all hadoop temp data \n rm -Rf /app/hadoop/tmp/*\nthen try again formatting",

It means that you should not use hadoop namenode -format but hdfs namenode -format instead, since it has been deprecated.",
