Constance Eustace commented on CASSANDRA-6224:
----------------------------------------------
I'm assuming this was a node synchronization problem of the schema, or it may
have been a very spotty AWS instance.
We haven't encountered this since.
> CQL3 Column family / tables "disappear", get unconfigured columnfamily errors
> -----------------------------------------------------------------------------

> Key: CASSANDRA-6224
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6224
> Project: Cassandra
> Issue Type: Bug
> Components: API, Core
> Environment: Cassandra 2.0.1 Amazon AWS Ubuntu Single-node
> Reporter: Constance Eustace

> We're seeing CQL3 tables seemingly arbitrarily disappear. Need to repair for
> prod meant we reconstructed the affected schema before nodetool repairs or
> similar attempts were done.
> It seems to take a few days to appear. Volumes are not tremendously high
> yet...
