Jonathan Ellis resolved CASSANDRA-2515.
---------------------------------------
Resolution: Not A Problem
0.8 isn't supposed to start up w/ a 0.7 config. diff the two sample files to
see what's changed; in this case it's CASSANDRA-1669.
> 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*
