Hi,
I'm using the 1.1.0 version for Giraph, the 0.3 for Gora, 2.4.0 for Hadoop and 0.94.8 for HBase. I've changed the options for the Input and Output format and the line command became: hadoop/bin/hadoop jar $GIRAPH_EXAMPLES_JAR org.apache.giraph.GiraphRunner -files /usr/local/giraph/giraph-gora/conf/gora.properties,/usr/local/giraph/giraph-gora/conf/gora-hbase-mapping.xml,/usr/local/hbase/conf/hbase-site.xml -Dio.serializations=org.apache.hadoop.io.serializer.WritableSerialization,org.apache.hadoop.io.serializer.JavaSerialization -Dgiraph.gora.datastore.class=org.apache.gora.hbase.store.HBaseStore -Dgiraph.gora.key.class=java.lang.String -Dgiraph.gora.persistent.class=org.apache.giraph.io.gora.generated.GEdge -Dgiraph.gora.start.key=0 -Dgiraph.gora.end.key=10 -Dgiraph.gora.keys.factory.class=org.apache.giraph.io.gora.utils.KeyFactory -Dgiraph.gora.output.datastore.class=org.apache.gora.hbase.store.HBaseStore -Dgiraph.gora.output.key.class=java.lang.String -Dgiraph.gora.output.persistent.class=org.apache.giraph.io.gora.generated.GEdgeResult -libjars $GIRAPH_GORA_JAR,$GORA_HBASE_JAR,$HBASE_JAR org.apache.giraph.examples.SimpleShortestPathsComputation -eif org.apache.giraph.io.gora.GoraGEdgeEdgeInputFormat -eof org.apache.giraph.io.gora.GoraGEdgeEdgeOutputFormat -w 1 And now I have this error :/ SLF4J: Class path contains multiple SLF4J bindings.
