I'm running a test cluster for development and evaluation of Cassandra. In
order to use the latest build of Hector (the 0.7.0 branch) I've need to move
from 0.6.5 first to 0.7.0-beta1 of Cassandra and then to the latest nightly
build (actually 2010-09-20_14-20-20). In order to move over I've followed the
following procedure:
1: get 0.7.0 running on all nodes, use schematool to update schema
2: confirm with cassandra-cli that the schema looks OK
3: Take down all nodes
4: on one node install nightly build
5:use config-converter to create config from 0.6.5 to nightly config
6: Change RackUnawareStrategy to SimpleStrategy in cassandra.yaml
7: start Cassandra
However I am still getting RackUnawareStrategy exceptions (output below).
Any ideas on the proper procedure ?
