How to access to HDFS of Pseudo-Distributed Hadoop

2012-09-28

There is a way to install hadoop as Pseudo-Distributed Operation. This is an easy way to try hadoop with one host, but you cannot access to HDFS from another host.

To improve it, change a bit thing as describing fs.default.name of core-site.xml with IP address to be accessible from another host.

Let’s say IP address of your host hadoop running is 192.168.10.20, you rewrite the value of fs.default.name as following.

<configuration>
  <property>
    <name>fs.default.name</name>
    <value>hdfs://192.168.10.20:9000</value>
  </property>
</configuration>

That’s all for the host.

After then, you can run hadoop command on your local machine. (Don’t forget configuration of your local machine)

$ hadoop fs -lsr hdfs://192.168.10.20:9000/
drwxrwxrwx   - hadoop supergroup          0 2012-09-28 16:32 /user
