As far as I can tell, our impala-cdh5-integration job loads data from snapshot and does an exhaustive test run. However, most integration problems in the past have show up when doing a full data load, so this job should do:
1. Full data load (not from snapshot)
2. Full exhaustive test run
As a result of not doing the full data load in that job, we have to manually run the full data load before upgrading our dependencies.
