Error starting a cassandra 0.8 cluster using the config file from an existing
0.74 cluster <upgrade scenario>
-------------------------------------------------------------------------------------------------------------
Key: CASSANDRA-2515
URL: https://issues.apache.org/jira/browse/CASSANDRA-2515
Project: Cassandra
Issue Type: Bug
Affects Versions: 0.8
Environment: 3-node Centos 5.5 cluster on rackspace
Reporter: Cathy Daw
Priority: Trivial
This is probably just a documentation bug, but very frequently I will see users
perform this same action when upgrading a cluster.
*Reproduction Steps*
* Install a 3 node 0.74 cassandra cluster
* Edit cassandra.yaml for each cluster
* Start 0.74 do some stuff, shut it down.
* Install 0.8 on the same cluster, but a different directory
* Copy the cassandra.yaml from the 0.74 cluster to the 0.8 cluster.
* Try to startup the 0.8 cluster
*Error starting an 0.8*
