Hello All!
Inspiting of including the jts jar in the class path of hadoop in
hadoop-env.sh, in the bashrc file of my system and in the classpath
variable while running the hadoop code through prompt, I am still getting
the error as Class not found exception for the *
com.vividsolutions.jts.io.ParseException*
*
*
*Please help me out!*

Thanks & Regards,
