http://localhost:50070 does not work HADOOP

Question

I already installed Hadoop on my machine \"Ubuntu 13.05\" and now I have an error when browsing localhost:50070 the browser says that the page does not exist.

Answer 1

For recent hadoop versions (I'm using 2.7.1)

The start\stop scripts are located in the sbin folder. The scripts are:

• ./sbin/start-dfs.sh
• ./sbin/stop-dfs.sh
• ./sbin/start-yarn.sh
• ./sbin/stop-yarn.sh

I didn't have to do anything with yarn though to get the NameNodeServer instance running.

Now my mistake was that I didn't format the NameNodeServer HDFS.

bin/hdfs namenode -format

I'm not quite sure what that does at the moment but it obviously prepares the space on which the NameNodeServer will use to operate.
