Hi,
I've seen recent posts saying it was possible to upgrade directly from
0.6 to 1.0. But how?
I ran "nodetool drain" on all my nodes and shut them down.
However, there is not config-convert tool anymore. Since I basically
using the default config, is it important? Or is it OK to just use the
default one and change the few settings I need?
Also, there is no schematool anymore either. So how do I load the
schema? Can I just create one using cassandra-cli? Will cassandra then
load the existing data?
Last, I tried to start cassandra 1.0.5, I get the following error in
cassandra.log:
ERROR 11:41:19,399 Exception encountered during startup

Then cassandra exits so I can't run nodetool repair (or create the
schema if that's the problem).
So how should I proceed?
Or maybe I misread the previous post and I should actually do 0.6->0.7->1.0?
Thanks,
Jehan
