rather would like to deploy the JDBC library into HADOOP_HOME/lib,
because it is rather static and other MR-jobs might depend on that as
well. The interesting thing is, when working with the Cloudera VMWare, a
reboot after copying the library into HADOOP_HOME/lib helped. So, how
are you deploying your MR-jobs into a real/live cluster without the need
to restart something?

A reboot or do you mean a restart of your MR cluster?  Additions to the
HADOOP_HOME/lib directory require a restart for them to show on the
general CLASSPATH.
