Where are the files after I installed a deb package
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 to?
