typo in install script URL?

[cmosetick]

Hi Albert,
I noticed that the current version of install-cassandra-tarball.sh on master has this in the $URL

www.apache.dist

I'm not aware of a .dist TLD being live yet.
I get a not found:

host www.apache.dist
Host www.apache.dist not found: 3(NXDOMAIN)

I'll create a pull request with www.apache.org/dist for this.
Apologies in advance if I'm missing something obvious here.

Here was that pull request:
