patch by Jeffrey Wang; reviewed by jbellis for CASSANDRA-2490
> DatabaseDescriptor.defsVersion should be volatile
> -------------------------------------------------
>
> Key: CASSANDRA-2490
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2490
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7.0
> Reporter: Jeffrey Wang
> Assignee: Jeffrey Wang
> Priority: Minor
> Fix For: 0.7.5
>
>
> (Probably affects other versions, but I am on 0.7.3).
> DatabaseDescriptor.defsVersion should be protected by volatile since it is
> written to and read by multiple threads from unsynchronized methods. This can
> manifest itself in schema agreement never occurring due to a node
> broadcasting the wrong schema version.
