Hi there,
I read a lot of Cassandra's high scalability feature: allowing seamless
addition of nodes, no downtime etc.
But I wonder how one will do this in practice in an operational system.
In the system we're going to implement we're expecting a huge number of writes
with uniformly distribut

Hi again,
some more remarks.
I renamed the commitlog directory on the third node so that cassandra cannot
see it on startup.
Now the node starts fine. The problem seems to have something to do with the
commitlogs...

Hi,
I'm using Cassandra 0.7.4 on a three node cluster. The cluster was setup
yesterday as a fresh installation (no upgrade).
The cluster is installed beside a hadoop cluster (I want to discover how
cassandra works together with hadoop's map/reduce feature).
After loading some test data into th
