Yeah. I haven't changed anything with the standard Giraph stuff. I just made my own vertex and and VertexInputFormat. We are in a 64bit environment. . .is it possible that building a jar with 32bit tools would be a problem? I wouldn't think so, since that addressing native-dependency issues was sort of the *point* of java. . .but, this seems really odd to me. Are there some dependency restrictions that I should know about? We have to use Jackson 1.6 (because we use cloudera distribution of hadoop), and there are other libraries we use. Thx again for the feedback.
