URL: https://issues.apache.org/jira/browse/GIRAPH-351
Project: Giraph
Issue Type: Improvement
Reporter: Avery Ching
Right now we get a cryptic error message when we know that there is no input!
2012-09-28 13:45:20,410 INFO org.apache.giraph.graph.BspServiceMaster:
generateInputSplits: Got 0 input splits for 100 workers
2012-09-28 13:45:20,410 WARN org.apache.giraph.graph.BspServiceMaster:
createInputSplits: Number of inputSplits=0 < 100=number of healthy processes,
some workers will be not used
But the job keeps on going and the workers get the exception
