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.
