The connect exception is fine, it usually takes more than one connect
attempt to zk. The reason your job failed is due to not having enough
simultaneous map tasks on your Hadoop instance.
See http://svn.apache.org/repos/asf/giraph/trunk/README for details on
running in pseudo-distributed mode.

Hello, everybody.
I'm trying to run the shortest paths example with the command below:
hadoop jar
giraph-0.2-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependencies.jar
org.apache.giraph.GiraphRunner
org.apache.giraph.examples.SimpleShortestPathsVertex -if
org.apache.giraph.io.JsonLongDoubleFloatDoubleVertexInputFormat -ip
shortestPathsInputGraph -of
org.apache.giraph.io.JsonLongDoubleFloatDoubleVertexOutputFormat -op
shortestPathsOutputGraph -w 3
However, it didn't work. In jobtracker I found that some jobs failed.
I had 4 killed tasks. Below you can see the log of the first task. I
got a ConnectException. Does anyone have some ideia why this
connection was refused? Thanks in advance.
