> Key: CASSANDRA-6862
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6862
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: 2.0
> Reporter: Oleg Anastasyev
> Assignee: Oleg Anastasyev
> Fix For: 2.0.7

> We have a large cluster with several hundreds nodes in 1 ring. Sometimes,
> especially after massive restarts, schema versions reported on different
> nodes mismatch.
> Investigated and found, that difference is not in schema itsself, but in
> thombstones (different nodes have different set of thombstones applied to
> system tables).
> Fixed by digesting schema with thombstones removed first.
