QA: When you try to run the Hadoop verification script, you get a rxCompleteClusterJob error

It is useful to check the following items in this case - the problem is an issue with the Hadoop configuration on the cluster.

1. Ensure that the local share directory '/var/RevoShare/$USER' exists on each cluster node.

2. Ensure that the directory '/var/RevoShare/$USER' exists on each cluster node in HDFS.

3. Make sure that the test dataset 'AirlineDemoSmall.csv' already exists in HDFS, before running the verification script.
