Hello David, Thank you for responding to my help. I have only been using version 0.11.2. I have to run grep in the single node as illustrated in the manual online and it looks successful. Doesn't the 'bin/hadoop jar hadoop-0.11.3-dev-examples.jar grep /bar/ac /tmp/ac foo' test the single node mode only? Because toward the end of the manual the distributed version of sample Grep is mentioned as "bin/hadoop org.apache.hadoop.samples.Grep myinput myoutput 'dfs'" I am trying to make sure it runs on 2 nodes before I add more machine to it. Thank you.
