Problems running hadoop on mac osx with default example

Make sure that you turn on Remote Login under System Preferences then File Sharing:

enter image description here

In order to check if it runs try jps command from command line. You should get something like:

43730 TaskTracker43674 JobTracker43730 NameNode43582 DataNode43611 SecondaryNameNode43821 Jps

And now try some of the hadoop examples:

$ hadoop jar /usr/local/Cellar/hadoop/2.3.0/libexec/hadoop-examples-*.jar pi 10 100
