Hadoop points at file:/// not hdfs:///

When I install CDH 4.5 using Whirr 0.8.2, hadoop points at file:/// not hdfs:///. Therefore, ‘ssh’ to the client node that is the last ssh of whirr. Then, I need to update Hadoop’s core-site.xml by adding its namenode, which is at /etc/hadoop/conf

 fs.defaultFS
 hdfs://hadoop-namenode:8020

For example, if a name node’s local ip address is 10.80.221.129

 fs.defaultFS
 hdfs://10.80.221.129:8020

Now you can see the HDFS directories and files. If you ssh to other nodes, you have to change other nodes’ core-site.xml too.
