Hi guys, I am a  student of C&S and a beginner of HAMA. When I test HAMA
pagerank with the input file that download from the website(
http://hama-shortest-paths.googlecode.com/svn/trunk/hama-gsoc/files/pagerank/input/pagerankAdjacencylist.txt),
there is always terminated with a NullPointerExceptions. But when I use the
input file with my own's instead, the program can give the right answer. I
checked the HAMA wiki, found nothing about this problem. So, I need your
help. Thank you very much ! And sorry for my English.
