Error: Could not find or load main class hdfs
Hello,
I am trying to run the WordCount example using Hadoop 2.2.0 on a single node. I tried to follow the directions from http://nextgenhadoop.blogspot.in/2013/10/steps-to-install-hadoop-220-stable.html. However, when I type in the command bin/hadoop hdfs -copyFromLocal input /input, I get Error: Could not find or load main class hdfs. I am very new to this and have no idea what is going on. Any help would be greatly appreciated!
Thanks,
Ronnie
