I'm an Ubuntu user and I install packages with the apt-get. For example:
sudo apt-get install hadoop-0.20
After I install the package, there will be files in /usr/bin, /usr/lib/hadoop etc. Are there any commands can show out where exactly the package installed its files?

Yes, use the dpkg command like
dpkg -L hadoop-0.20
The converse question (finding the package providing a given file) is answered with e.g.
dpkg -S /usr/include/gc/gc.h

PS. Ubuntu (and other Linux distributions, eg Mint) is a derivative of Debian.

2dpkg will not tell you about config files and/or files created by the postinst script if the package. If you need to be really sure you get all files if a package, you will also need to examine its packaging scripts. – tripleee – 2012-07-27T11:43:27.203

You can list the installed files for a package by passing the --listfile flag to dpkg. For example, if your package is actually named "hadoop-0.20" then:
dpkg --listfiles hadoop-0.20

Or in a shorter form dpkg -L as I already answered. – Basile Starynkevitch – 2012-07-27T08:48:16.970

What files are installed on your system varies from package to package. To be 100% sure you should take a look into the .deb package yourself. Download the package first.
First you need to extract the .deb archive:
ar vx mypackage.deb
Now this should result in three new files: debian-binary, control.tar.gz and data.tar.gz. You're interested in the last one.
Now you can extract it as well using tar:
tar xzvf data.tar.gz
Now you can browse the package content freely. Look for any makefiles, install scripts and such like to see where things gets installed.
Try the man pages of the apt command family. For example: man apt-get – None – 2012-07-27T08:16:56.390
