Subject Re: Install Cassandra on EC2
Date Thu, 04 Aug 2011 06:03:31 GMT
HI Aaron,
Thanks for your replay.

I've already saw that, but at the moment I'm interesting in installing
Cassandra from scratch - I want to learn.
well, yesterday I've installed 1 node - now I'm looking on how to add more
nodes and read more about Cassandra's tools (node reaper etc.)

Thanks!
