Subject Re: Problem with simple shortest path
Date Fri, 17 Jul 2015 13:57:42 GMT
Hello Vandana

If you are working on a single machine, you have to set not to split the master and worker
machines.

To do so, add ‘-ca giraph.SplitMasterWorker=false’ to the command you use to launch the
job.

Hope this helps.
