Hi Chethan,

This is unusual but I seem to remember that I came across this once.
Could you do 'ant clean' + ant job and try again? What version of Java
do you use?

Hi Julien,

Did "ant clean" and then "ant job". tried again but same exception.

java version : java version "1.6.0_26"

my doubts

1. the "Generating the corpus" command should run under hadoop directory right.
2. what all the basic software requirements.

Hi Julien,

java version :  java version "1.6.0_26"

hadoop is configured with "java-6-sun", but i am sure that "jnioche /
behemoth" is using which version of java. how to know.....?

See https://github.com/jnioche/behemoth/wiki/behemothcompilation for the prerequisites

You should be able to call it from anywhere as long as 'hadoop' is on your path and you are pointing to the location of the job file.

Just regenerate a brand new job file with mvn clean install.
