FAQ
Hi everyone

Follow up on my previous message.
I played around a bit tried supressing and changing what machine had the
jobtracker in cloudera manager 4.1.1.
But on start everything looks fine the manager says started and good to go.
However if I look in the jobtracker log and tasktracker logs I see errors:
and a frightening nullpointer.

Have I missed a step not installed a package, is unbuntu 12.04 not
supported for mapreduce.
If anyone has an idea what I am doing wrong.
