Please upgrade the Commons Configuration jar
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!
