Thanks for the explanation Arun!

Can this explanation be added to the project page:

http://hadoop.apache.org/bylaws.html

It seems that Hadoop differs a bit from how HTTP does this; would be =
worth documenting.  For example, the HTTP page Owen links says this:

"Once the release has reached the highest-available designation (as =
deemed by the RM), the release can be moved to the httpd distribution =
directory on apache.org"

However, it seems that even the alpha and beta quality releases are =
distributed as widely as the stable ones.  HTTP also uses the phrases =
"alpha", "beta", and "general availability" while Hadoop uses "alpha", =
"beta", and "stable".

When I go through the project webpage (http://hadoop.apache.org/), I =
don't see any branding to indicate the current stability until a couple =
of clicks in (http://hadoop.apache.org/common/releases.html).  Even =
then, it's the second page in and not very distinguished (took me a few =
minutes to actually find it when I was looking for it).  A little bit of =
marketing would go a long way here to get folks to avoid 0.21, for =
example.

Thanks!

Brian
