I am getting HTTP 404
error regardless of C* version I choose. I tried,
$ ccm create test -v 3.0
$ ccm create test -v 2.1
In both cases I get the error,
16:42:23,601 ccm WARNING Downloading 2.1 failed, trying to build from git instead.
The error was: Invalid version 2.1 (underlying error is: HTTP Error 404: Not Found)
http://git.apache.org/cassandra.git git:cassandra-2.1
Try running,
$ ccm create test -v 3.0.0
$ ccm create test -v 2.1.0
