Hi, I am new to hadoop, and tried to setup a distributed hadoop system. But when I tried to run the example job, it stack dumped with the following exception:
org.apache.hadoop.ipc.RemoteException: java.io.IOException: Unknown protocol to name node: org.apache.hadoop.mapred.JobSubmissionProtocol I setup hadoop 0.14.1 on two machines, where one acts as both the name node and job tracker, while the other one is just a slave When I set it up on a single machine and ran it standalone, it worked fine. Please let me know if more information is needed to help troubleshoot. Thanks! -- Jim
