new to hadoop and first question

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

Make sure all the config settings are OK and you have proper dns
resolution. Modify the line "127.0.1.1" in your /etc/hosts file to
"127.0.0.1". And, I completely agree with Vinod sir. 0.14 is ancient now.

You are pointing your JobClient to the Namenode. Check your
mapred.job.tracker address and make sure it points to the correct
JobTracker node.

Also 0.14 is very very old. Please use 1.* releases.

Hi,

I'm right now facing the same issue(the same protocol error) while setting up 
hadoop on single  standalone machine. Since you were successful on setting it 
up on standalone machine, please guide me as how to fix it. 


Re: new to hadoop and first question

Posted by Michael Bieniosek <mi...@powerset.com>.
It looks like you are treating a jobtracker as a namenode.  Make sure fs.default.name is set to a namenode's address.  By default, namenodes run on port 10000, while jobtrackers run on port 10001.
