Not able to acess Namenode web URL

Question

I tried accessing the web url of namenode with the namenode IP. It throwed an error HTTP ERROR 404 Problem accessing /dfshealth.jsp. Reason: NOT_FOUND

I am able to access the Namenode web url with the hostname.

/etc/hosts file:

127.0.0.1       localhost

192.168.10.103  impc2390


192.168.10.102  impc2359

192.168.10.101  impc2391

192.168.10.111  impc2394

192.168.10.104  impc2361

I tried 192.168.10.104:50070
It throwed an error that page not found

I tried with impc2361:50070
It worked fine

Why am I not able to access the page with Ip of the computer?

Answer 1

The reason behind HTTP ERROR 404 Problem accessing /dfshealth.jsp. Reason: NOT_FOUND error is because Namenode web UI is trying to access dfshealth.jsp page which has been removed in the latest hadoop releases.

When you enter NamenodeIP and port 50070 and hit enter, dfshealth.jsp must have been appended. May be you had older version of hadoop and your broswer had cached the address.

The solution to this would be either you clear the browser cache or append /dfshealth.html#tab-overview as

192.168.10.104:50070/dfshealth.html#tab-overview

Hope to see your problem solved with this answer.
