I created a page for my Hadoop notes and will keep those up to date with what I am experimenting.
I will post short articles on what I have done and where I am facing challenges.
I think that using the OpenJDK is a mistake so I am testing with the Oracle JVM to see if it fixes some of the issues I am facing.
I have also upgraded to Fedora 20 which should not change much in how Hadoop works. The only I have noticed is an error because the temp directory is gone. I will have to investigate why that is preventing the namenode from starting. Might have to move the temp outside of /tmp to avoid this issue.
