[SOLVED] Giraph is waiting infinitely after first superstep (-1).

Usually, it works well if you don’t classify capital and small letter, hostname in “/etc/hostname” and “/etc/hosts” in hadoop eco system. But in Giraph if you don’t classify capital and small letter, it will stop without any Error and Debug message. Be sure to classify capital and small letter

Giraph is waiting other worker and not working after superstep

I try to use Giraph on fully distributed hadoop eco system. But when I executed SimpleShortestPathsComputation example, but master is waiting infinitely at superstep -1. This is my logs at master. 2014-01-21 04:19:45,255 DEBUG org.apache.giraph.bsp.BspService: process: Got a new event, path = /
