Subject [jira] [Commented] (CASSANDRA-6862) Schema versions mismatch on large ring
Date Fri, 31 Oct 2014 17:39:34 GMT

sankalp kohli commented on CASSANDRA-6862:
------------------------------------------

This will cause problems for 1.2 to 2.0 upgrade as 1.2 will add tombstones and 2.0 won't.

> 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.
