> Note that the Sqoop tar bundle does not contain the JDBC connector jar. I 
> think the problem here maybe that the mysql connector jar added to libjars 
> isn't available to the Sqoop tool which first connects to the database 
> through JDBC driver to collect some table information before running the MR 
> job. libjars will only add the connector jar for the MR job and not the local 
> one.
> NO PRECOMMIT TESTS
