I found an odd error in the Quick Start guide on the line when you create the Oozie DB:
$ bin/ooziedb.sh create -sqlfile oozie.sql -runValidate DB Connection.
Check DB schema does not exist
The error is that "Validate DB Connection" should be on it's own line. Oddly enough, if you look at the DG_QuickStart.twiki in the repository, the line is correct:
140 $ bin/ooziedb.sh create -sqlfile oozie.sql -run
142 Validate DB Connection.
