Answer 1

Had come across the same exception. It was to do with the user permissions. The user which you are using to run oozie, check its permissions.

Answer 2

This might happen if you're using the wrong jobTracker port. By default oozie examples use port 8021 (MR1), but if you're using MR2/YARN you need to change it to 8032. This value is set in your job.properties file.

If you want to update all of the example jobs at once, from your examples directory run the following:

sed -i 's/8021/8032/g' examples/apps/*/*.*

Make sure to overwrite the example files in HDFS with the updates (you might even want to cat the job.properties file in HDFS to confirm it has been overwritten).
