Re: Hadoop 0.19 over OS X : dfs error
Well its strange.. although I changed default JAVA environment to Java 6 64bit but still my /Library/Java/Home was pointing to java 5. So in config/hadoop_env.sh I changed the path of JAVA_HOME to actual path i.e /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home .Its working now.
