Thanks all for your reply.. Actually i am working with an algorithm in which single source shortest path algorithm runs for thousands of vertices .suppose on an average for one vertex this algo takes 5-6 supersteps,then for thousands of vertices,count of superstep is extremely large..In that case at run time following error is thrown...
ERROR org.apache.giraph.master.BspServiceMaster: superstepChosenWorkerAlive: Missing chosen worker Worker(hostname=kanha-Vostro-1014, MRtaskID=1, port=30001) on superstep 19528 2014-01-28 05:11:36,852 INFO org.apache.giraph.master.MasterThread: masterThread: Coordination of superstep 19528 took 636.831 seconds ended with state WORKER_FAILURE and is now on superstep 19528 2014-01-28 05:11:39,446 ERROR org.apache.giraph.master.MasterThread: masterThread: Master algorithm failed with ArrayIndexOutOfBoundsException java.lang.ArrayIndexOutOfBoundsException: -1 Any ideas??
