Dears,

1. I got the warning message when I type command "./start-all.sh" on NN.
WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform...

2. "ldd" check got as below information:

Hadoop version: 2.2.0
OS: Ubuntu 10.04 LTS


who know what happen? how to solve it.

many thanks.

First, you might need to run ldconfig to update the libraries.



Since you're using Ubuntu 10.04, try to check your libc6 package.
Maybe it's better to upgrade to Ubuntu 12.04

Thanks Jazz for the share.
as you said. maybe try to upgrade to Ubuntu 12.04 it will be better.
I still got some issue. XD

Thanks!

I'm not quite sure about the issue of libjvm.so
maybe you could try "ldconfig" as root.
