I'm new to hadoop and I use the cloudera quick start vm. I've made a MapReduceJob in java, bud when I run the MRJ using oozie on the cloudera vm, I get an minor major versions error? I think this is because of the uses java versions. For the MRJ I need to use 1.7. So how can I update the cloudera vm to java 1.7?

(p.s.. Spell check doesn't know cloudera?)
