Can't access hadoop with ip address

Question

I'm following this guide for installing hadoop in centos.

Everything works normal when I run hadoop and I compare it with the guide also, but when I try to access mine with ip address like 192.168.0.1:50070 then nothing works.

Here is the output when I run had:

bash-4.2$ start-dfs.sh
14/10/15 16:28:30 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

Do you think I have to configure IP somewhere to access them? My configuration is exactly the same as above link, even the xml files...

Answer 1

Did you tried to disable the firewall/make an ip tables line for it on the master/slaves?

for centOS6.5, try:

service firewall stop

to disable the firewall. If it works properly, you just need to add the allowance to your iptables.

Also, CentOS has the SELinux. I would advice turning it off and check if it keeps with an error.
