Subject problem on connecting two hadoop nodes
Date Sun, 06 Dec 2009 03:33:46 GMT
Hi All,
I am trying to set up a hadoop cluster. I have started hdfs on one machine,
while mapreduce on the other machine. when I try to use "bin/hadoop fs -ls",
the following error is thrown.
09/12/06 03:08:20 INFO ipc.Client: Retrying connect to server: tang1/
143.215.206.12:9000. Already tried 0 time(s).
09/12/06 03:08:21 INFO ipc.Client: Retrying connect to server: tang1/
143.215.206.12:9000. Already tried 1 time(s).
...

More specific, the following is what I have done to start up the
environment. On one machine, I use
bin/hadoop namenode -format
bin/start-dfs.sh

On the other machine, I use
bin/start-mapred.sh

I can ssh from one machine to the other, (though w/ passwd, but I dont know
how to make ssh connect password-free..).
Please let me know what the error is about, and if you have similar
experience, your help is appreciated, thanks for your attention.
