Hello everybody I’m here to share my experience with the error “Worker failed during input split (currently not supported)”. I have seen several help requests in this mailing list asking for help for this kind of situation, so I’d like to share my experience: it could help at least some of you. This is the incriminated error log: > barrierOnWorkerList: Missing chosen workers [Worker(hostname=01hw789772, > MRtaskID=1, port=30001)] on superstep -1 > 2014-11-25 20:55:13,590 ERROR org.apache.giraph.master.MasterThread: > masterThread: Master algorithm failed with IllegalStateException > java.lang.IllegalStateException: coordinateVertexInputSplits: Worker failed > during input split (currently not supported) In my case the error was related to Giraph-904 bug (https://issues.apache.org/jira/browse/GIRAPH-904). In fact, in the first line the system logs that there are missing workers (and my hostname was written in only lowercase chars, while my former hostname had both lowercase and uppercase chars). I managed to solve my issue by using a hostname made up by only lowercase chars.
Hope this helps someone: in the meantime, I’ll report that this issue is still open (and not fixed) in Jira. ~~~~~~~~~~~~~~~~~~~ Ing.
