Hadoop latest version in binary?

when I was about to download the latest stable version of hadoop as of today (06/27/2014), I find that there is no bin.tar.gz available. I see the following. I am not sure which one I should download.

hadoop-2.2.0-src.tar.gz     07-Oct-2013 02:46   19M  
hadoop-2.2.0-src.tar.gz.mds 07-Oct-2013 02:46  1.1K  
hadoop-2.2.0.tar.gz         07-Oct-2013 02:46  104M  
hadoop-2.2.0.tar.gz.mds     07-Oct-2013 02:47  958

First of all, what is the difference between all the files above. It seems src.tar.gz is only 19M but tar.gz is 104M. which is the preferable one to work with? Previously I used the bin.tar.gz for 1.2.2 as follows. but that is not available with 2.2.0 version. why is that?

for 1.2.X I used bin.tar.gz

hadoop-1.2.1-bin.tar.gz       22-Jul-2013 18:27   36M
