Hi,
well, sort of, we have some other networking issues now that forbid us
from actually testing the change of the port.
I will let you know as soon as all is tested.
Thanks to everyone for their help,
George

George,
Good to know. That'd indeed have lead to wrong bind/listen. Are you
out of DFS troubles now?

Hi,
we have made some progress with this. One of the problems was that:
-etc/hosts master alias was set to localhost
So we changed the core-site xml to have directly the public IP.
BR,
George

Hi,
it seems to be working fine, and the telnet also works...:-(

George,
Could you ensure that your 8090'd NameNode starts up fine? If yes, can
also you telnet to that "host port" from your remote node - that
should tell you if your firewall is at issue again?

Hi,
the main issue that we are trying to connect a datanode from a remote
domain
to the master node that is behind a firewall that does not have 8020
open.
We change the port from the core-site xml to 8090 and restart.
But when we try to start hdfs, it seems that all services are started,
datanode is listed in the jps, however in the datanode logs we get the
following error:
2011-06-02 12:41:21,378 INFO org.apache.hadoop.ipc.Client: Retrying
connect to server: master/xxx.xxx.xxx.xxx:8090. Already tried 3
time(s).
and it finally gives up. Thanks for the link, it is very helpful to have
all
this info concentrated.
BR,
George

George,
Could you additionally describe the issues you're facing right now
w.r.t.
ports?
If you need a fuller port number reference, we have a blog post here
you can get them from:

Hi,
thanks for the reply, we tried this with a definitely open (from a
firewall
pov) port but still did not work. Maybe something else in addition is
needed?
Thanks,
George

Are there anywhere instructions on how to change from the default
ports
of Hadoop and HDFS? My main interest is in default port 8020.
I think this is part of fs.default.name. You would go into
core-site.xml
and add (or change)
<property>
<name>fs.default.name</name>
<value>hdfs://[namenode]:[port]</value>
</property>
I'm sort of new to this myself, so if I'm wrong I hope someone will
correct me.
