> On line 133 of the hadoop shell wrapper, CLASSPATH is set as:
> CLASSPATH=${CLASSPATH}:${HADOOP_CLASSPATH}
> Notice that the built-up CLASSPATH, along with all the libs and unwanted JARS
> are pre-pended BEFORE the user's HADOOP_CLASSPATH. Therefore there is no way
> to put your own JARs in front of those that the hadoop wrapper script sets.
> We propose a patch that reverses this order. Failing that, we would like to
> add a command line option to override this behavior and enable a user's JARs
> to be found before the wrong ones in the Hadoop library paths.
> We always welcome your opinions.
