Hi,
We hava a mapred setup on 4 machines. (1 namenode and 3 datanodes)
I can access the file system from these machines without any problem.
However, when I tried to write a file to the NDFS on a machine other than
these 4 machines
I got the following error:
~/nutch-mapred/bin$ ./nutch ndfs -put nutch nutch

>From the same machine I was able to list the files and create directories.
What may be the problem?
Thanks.
