Hi everyone, I have already run the SimpleShortestPathsComputation on single node pseudo-distribution and I am currently trying to run it on a 2 node cluster on Ubuntu 14.04. But every time I got the following Error: (Complete Logs below)
"ERROR org.apache.giraph.master.MasterThread: masterThread: Master algorithm failed with IllegalStateException java.lang.IllegalStateException: connectAllAddresses: Too many failures (1000)." Which seems to be the result of the NettyClient not being able to connect with the other node on port 30001 resulting in "java.net.ConnectException: Connection refused: rofti/192.168.0.103:30001". I already tried to open the port on both nodes as described here: http://mail-archives.apache.org/mod_mbox/giraph-user/201310.mbox/%3CCAAcgib35tQyROodNQrE3Se_39JsT5MiQVP=4v==x10jtouf...@mail.gmail.com%3E and made sure that all host-names are written in only lowercase letters. But that didn't change anything. I really appreciate any help you guys can offer.
