Hadoop install libs should be consistent with hadoop-core maven dependencies.
I found this error because I was using a feature available in commons-lang.2.6
that was failing when executed in my hadoop cluster (but not with m pigunit
tests).
A last remark, it would be nice to display the classpath used by hadoop cluster
while executing a job, because these kinds of errors are not easy to find.
