hadoop dfs -ls hdfs://Atlas.sollix.com:8020/ fails
Hi Everybody
I installed the hadoop on a 5 node cluster using the Cloudera's SCM. The
following is the setup.
Atlas.prodigy.com -- Namenode and Data Node
Pan.prodigy.com -- Secondary Namenode and Data Node
Prometheus.prodigy.com-- Data Node
Ulysys.prodigy.com--Data Node
Blade.prodigy.com -- Data Node
The Installation has created a user named hdfs on all the five
installations. I logged in using the root user and changed to hdfs user
using #su - hdfs and executing the below command on the Namenode and it is
listing me the HDFS file system files like below.
hdfs@Atlas> hadoop fs -ls hdfs://Atlas.prodigy.com:8020/
Found 4 items
drwxr-xr-x - hbase hbase 0 2012-01-11 09:47 /hbase
drwxr-xr-x - hdfs hadoop 0 2012-01-24 07:10 /home
drwxrwxrwt - hdfs hadoop 0 2011-12-19 09:58 /tmp
drwxr-xr-x - hdfs hadoop 0 2011-09-22 05:31 /user
Where as when i execute the same command on the other nodes terminal it is
giving me the following error.
hdfs@Pan> hadoop fs -ls hdfs://Atlas.prodigy.com:8020/
12/01/24 10:18:52 INFO ipc.Client: Retrying connect to server:

Atlas.prodigy.com/10.1.151.122:8020. Already tried 5 time(s).
Also I am not getting any information when i execute the report on any of
the nodes
hdfs@Atlas:~> hadoop dfsadmin -report
hdfs@Atlas:~>
I haven't changed any settings after the installation. I am able to login
to the admin console and see that all the nodes are in good state.
I hope that i explained the problem clearly and expect some suggestion as
soon as possible
Thanks in Advance
Zaki

Do you have firewall enabled on any of these systems?
