hadoop native library only shows up with sudo

Question

I'm trying to set up hadoop and put in all the env variables in my bashrc on an Ubuntu. The problem is if I do the following in a terminal,

hadoop checknative

I get the response:

14/07/23 01:48:10 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your    platform... using builtin-java classes where applicable
Native library checking:
hadoop: false
zlib:   false
snappy: false
lz4:    false
bzip2:  false

but if I use sudo

sudo hadoop/bin/hadoop checknative

I get the response:

14/07/23 01:48:36 WARN bzip2.Bzip2Factory: Failed to load/initialize native-bzip2 library system-    native, will use pure-Java version
14/07/23 01:48:36 INFO zlib.ZlibFactory: Successfully loaded & initialized native-zlib library
Native library checking:
hadoop: true /home/ubuntu/hadoop/lib/native/libhadoop.so.1.0.0
zlib:   true /lib/i386-linux-gnu/libz.so.1
snappy: false
lz4:    true revision:99
bzip2:  false

What should I do so I see the libraries without sudo? Am I going to have to use root always?

Try: chown -R yourusername /hadoop/bin/hadoop if you want to run as youself. — John Powell, Jul 23 '14 at 06:54
Also, see this, which explains how to run as root, but without a password. http://unix.stackexchange.com/questions/18830/how-to-run-a-specific-program-as-root-without-a-password-prompt by changing sudoers entry. — John Powell, Jul 23 '14 at 06:58
i already took ownership of the whole hadoop dir. it didn't change anything. — Majid alDosari, Jul 23 '14 at 15:22
i shouldn't have to run it as root. plus all the guides that i've followed didn't use sudo for running hadoop. — Majid alDosari, Jul 23 '14 at 15:51
this post is not a duplicate. i am aware of the problem with a 64bit linux . the ubuntu was 32 bit. furthermore, it doesn't explain why it just works with sudo. — Majid alDosari, Jul 24 '14 at 18:48
