I've been trying to install hadoop 2.7.0 on Ubuntu but when i enter the hadoop namenode -format command i get the following message:
Error: Could not find or load main class org.apache.hadoop.hdfs.server.namenode.NameNode
I've triple checked all the configuration files but i can't seem to find where the problem is.
I followed this tutorial : http://www.bogotobogo.com/Hadoop/BigData_hadoop_Install_on_ubuntu_single_node_cluster.php
Can anyone please tell me why is this not working??
