Subject Zookeeper exception while running SimpleShortestPathsVertexTest
Date Fri, 08 Mar 2013 20:31:18 GMT
Hi folks,

I am trying to run the SimpleShortestPathsVertexTest example
introduced by the unit testing tool as part of
(https://issues.apache.org/jira/browse/GIRAPH-51) and see the below
zookeeper exception while running the testToyData method. I can run
giraph applications from the command-line and have confirmed that the
worker node can bring up zookeeper ok. Is there a configuration step I
am missing while running the unit test tool?

Thanks,
Ameet
