The 0.23.7 distribution of Hadoop still contains the 1.6 version of Commons Configuration.
It is a version released on 2008-12-25, almost *five years* ago. Could you at least upgrade it to 1.8 (three years old)? 1.6 is giving us constant headaches as it misses a method java.lang.NoSuchMethodError: org.apache.commons.configuration.PropertiesConfigurationLayout.setGlobalSeparator(Ljava/lang/String;)V that is used by the DSI utilities, WebGraph, MG4J to generate bash-sourceable property files. I have replaced 1.6 with 1.8 directly into the Hadoop distribution and works like a charm. Thanks! seba
