Hi, maybe somebody could help me with this.
What I want to do is using Hadoop Streaming for just executing the same program with different parameters. I'm using the network simulatioin software Omnet++ and I want to run this simulation in parallel. Omnet Programs can be executed from a linux shell, the just need an omnetpp.ini file for configuration. So first step for me is, to get omnet running on hadoop with a simple example and the same parameters. So which hadoop-paramters I have to use when I start Hadoop Streaming? (I think hadoop streaming is the right way to do this, or not?) Acutally I try something like this, but the streaming job fails. bin/hadoop jar hadoop-0.18.3-streaming.jar -input /input/fifo -output /output/fifo -mapper "/home/simon/omnetpp-4.0/samples/fifo/fifo -u Cmdenv -c Fifo1" -file /home/simon/omnetpp-4.0/samples/fifo/fifo -reducer NONE So the omnet program is just the mapper. - in /input/fifo is the omnetpp.ini file located, that omnet fifo example needs to run the job. fifo -u Cmdenv -c Fifo1 are the parameters to start omnet without the graphic interface. But also when I put these parameters into a shell srcipt and run the script with hadoop I get the same error. The omnet program is installed on all machines. Maybe I have to give the omnet.ini file in some other way to the omnet-fifo program? I don't know. I'm no programmer and I even don't know if this approuch goes into the right direction. For any hints or suggestions I would be very glad. P.S. Sorry for my bad english Simon Lorenz Karlsruhe Germany
