Hi All!
I’m trying to process a file to giraph that looks like this (tab delimited):
tamer 0.1 john 0.2 mike 0.3
where the vertex “tamer” is a source, and has a destination link to vertices
john and mike.
Here is the command I use:
hadoop jar
giraph-examples-1.2.0-SNAPSHOT-for-hadoop-1.2.1-jar-with-dependencies.jar
org.apache.giraph.GiraphRunner \
-libjars ${LIBJARS} org.apache.giraph.examples.SimplePageRankComputation \
-vif
org.apache.giraph.io.formats.TextDoubleDoubleAdjacencyListVertexInputFormat \
-vip /giraphinput/textinput.txt -vof
org.apache.giraph.io.formats.IdWithValueTextOutputFormat \
-op /giraphoutput/pagerank02122015-7 -w 1 -ca giraph.SplitMasterWorker=false \
-mc
org.apache.giraph.examples.SimplePageRankComputation\$SimplePageRankMasterCompute
But I get an error:
15/02/13 14:05:17 INFO utils.ConfigurationUtils: No edge input format

Any idea on how to fix this?
Thanks.
