Hello, thank you for the reply.
I checked the hosts list and all the name I am using is fully
resolvable. And I even tried to use ip address, but still obtain:
Retrying connect to server: camelot01-ib.doc.ic.ac.uk/10.100.1.1:9000.
Already tried 1 time(s)
....
Retrying connect to server: camelot01-ib.doc.ic.ac.uk/10.100.1.1:9000.
Already tried 10 time(s)
I read some post in internet, and thinking could it be my nadenode
problem? which port 9000 was not opened..
this is what happened when i do bin/start-*.sh
it shows: datanode running as process 32322. Stop it first.......is this
normal? why stop it first?
I checked the process list on the datanode, there are 3 java processes
running, but the port 9000 wasn't Listening...what is the possible cause?

Hello, after change the domain name, it still fails.
I just realise something:
when i run :
camelot01% bin/hadoop jar hadoop-0.12.3-test.jar testrpc
Well, I think you'd better check the file /etc/hosts.
for example,my computer name : wayne , so the file hosts may be like
this:
127.0.0.1 localhost
202.197.18.27 wayne
If you are not sure about this,just have a try to ping your computer
name.
