Hello!
my code works now, if I include gis jar in the classpath in the prompt
while compiling the code using javac and even in the HADOOP_CLASSPATH
variable in the hadoop-env.sh file.
But, since my code required only one jar, it worked. Now, if I got to
bundle all the jars and then include it in the classpath, how do i do it?
Also, to use the third-party jars, do I need to necessarily move them in
the hadoop/lib folder? Or they can be present anywhere..?

Thanks & Regards,
