Attachment: CASSANDRA-3849.patch
> Saved CF row cache breaks when upgrading to 1.1
> -----------------------------------------------
>
> Key: CASSANDRA-3849
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3849
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.1
> Environment: 1 node cluster running on branch cassandra-1.0. Ubuntu.
> both key and row caching were enabled.
> Reporter: Tyler Patterson
> Assignee: Pavel Yaskevich

>
> Enabled row and key caching. Used stress to insert some data. ran nodetool
> flush, then nodetool compact. Then read the data back to populate the cache.
> Turned row_cache_save_period and key_cache_save_period really low to force
> saving the cache data. I verified that the row and key cache files existed in
> /var/lib/cassandra/saved_caches/.
> I then killed cassandra, checked out branch cassandra-1.1, compiled and tried
> to start the node. The node failed to start, and I got this error:
> {code}
