HDFS help
Hi,
I am installed hadoop 1.0.2 on the Amazon EC2 and created the AMI. Then, i
logged into the instance i created from the AMI.
Then, i try to run the hadoop fs -ls command and getting the following
error.
Please help me in this regard, what am i doing wrong?
[root@domU-12-31-39-0A-28-31 conf]# hadoop fs -ls

Hello Pedamallu,
Your NameNode isn't serving on the right interface. What is your
fs.default.name? Clearly doesn't seem to be listening on
domU-12-31-39-0A-28-31.compute-1.internal/10.211.43.191
Also, consider using Apache Whirr when using Hadoop+EC2:
http://whirr.apache.org - Should make your life much easier.
