http://localhost:50070 not working in HADOOP

+1 vote

I have already installed Hadoop on my machine running Ubuntu 13.05 but while I am browsing the address "localhost:50070", I am getting an error that the page does not exist.

Can anyone tell me what should I do to resolve this?

Thanks in advance!

There are 2 case possible:

1. If you are running Hadoop version 3.0.0 then let me tell you that there was a change of configuration and http://localhost:50070 was moved to http://localhost:9870

2. If you are running Hadoop version 2.X, then what you can do is just stop all the daemon services, format the name node and again restart the services.

Following are the steps:

Step 1 : bin/stop-all.sh

Step 2 : bin/hadoop namenode -format

Step 3 : bin/start-all.sh

Hope, this will resolve your issue.

Thanks a lot 9870 was the problem :)
Thanks, issue with port number solved.
I am also facing same issue while browsing localhost:50070 .It says 'localhost refused to connect'.

I have installed hadoop version 3.2.1.

Can you please help me out?
And also how this no 50070 is decided?

In hadoop 3.x there is a change of configuration and http://localhost:50070 was moved to http://localhost:9870.

Port no is not decided by us. 50070 is the default NameNode web UI port (Although, in hadoop 3.0 onwards 50070 is updated to 9870).
