Hi, Initially, I got the version number error at the beginning. I found that JDK version was 1.5. It has been upgraded it to 1.6. Now JAVA_HOME points to /usr/java/jdk1.6.0_13/ and I am using Hadoop 0.18.3. 1. What could possibly be wrong? I checked the Hadoop script. Value of JAVA_HOME is correct (ie 1.6). Is it possible that somehow it is still using 1.5?
I'm going to guess the issue is that you need Hadoop 0.19.
2. The last step the clustering tutorial says "Get the data out of HDFS and have a look." Can you please point me to the documentation of Hadoop about how to read this data?
http://hadoop.apache.org/core/docs/current/quickstart.html towards the bottom. It shows some of the commands you can use w/ HDFS. -get, - cat, etc.
