If you're running without a real Hadoop instance, you'll need to blow
away the zk directories after running the first time. Hope that helps,

Hi,
I am exploring Giraph 0.1 and was able to download, build, and run all
the tests - all 58 passed.
I can also run the SimpleShortestPathsVertex test using the supplied
giraph jar. However, when I copy the java src file into eclipse and
build my own jar I get the following error which leads me to believe
that something is going wrong with the ZK setup.

BTW, I needed to add the following line to get this to run from my own
jar file...
job.setJarByClass(SimpleShortestPathsVertex.class)
Not sure if that is related but it seems that it will not run without
this (it can not find SimpleShortestPathsVertex.
Thanks,
Jon Bishop
