Hi Rodrigo, I am also new to giraph. But this error looks familiar. I ran into this when I was asking for more workers than available on the queue. Looks like it could find only 1 when u asked for 3.
Thanks, Tripti.

I'm running 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 Unfortunately, the output is not right. Some jobs were killed and I got this in the log: ERROR org.apache.giraph.graph.BspServiceMaster: checkWorkers: Did not receive enough processes in time (only 1 of 3 required). This occurs if you do not have enough map tasks available simultaneously on your Hadoop instance to fulfill the number of requested workers. What is going on? How could I fix this problem? Thanks in advance. Rodrigo Zerbini
