Hi Claudio... Thanks for your active response.. Still I have doubt.The giraph program which I am running is not the sample program given in the giraph examples,although the name looks the same. Ok I changed the name. Now the new name of the program I want to execute is try.java.
I compiled it successfully and stored the .class file in a directory named /home/hduser/try_classes and created a jar file named /home/hduser/try.jar from the try_classes subdirectory. Now I want to run this try.class file.For that I need to include this my own created jar file to the classpath.What should I do? Please help.
