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/
18.104.22.168:9000. Already tried 0 time(s).
09/12/06 03:08:21 INFO ipc.Client: Retrying connect to server: tang1/
22.214.171.124:9000. 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
On the other machine, I use
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.
