> Offline scrub does not migrate the directory structure on migration from
> 1.0.x to 1.1.x and causes the keyspace to disappear
> ----------------------------------------------------------------------------------------------------------------------------
>
> Key: CASSANDRA-5195
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5195
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.1.9
> Reporter: Omid Aladini
> Assignee: Jonathan Ellis
> Fix For: 1.1.9
>
> Attachments: 5195.patch
>
>
> Due to CASSANDRA-4411, upon migration from 1.0.x to 1.1.x containing
> LCS-compacted sstables, an offline scrub should be run before Cassandra 1.1.x
> is started. But Cassandra 1.1.x uses a new directory structure
> (CASSANDRA-2749) that offline scrubber doesn't detect or try to migrate.
> How to reproduce:
> 1- Run cassandra 1.0.12.
> 2- Run stress tool, let Cassandra flush Keyspace1 or flush manually.
> 3- Stop cassandra 1.0.12
> 4- Run ./bin/sstablescrub Keyspace1 Standard1
> which returns "Unknown keyspace/columnFamily Keyspace1.Standard1" and
> notice the data directory isn't migrated.
> 5- Run cassandra 1.1.9. Keyspace1 doesn't get loaded and Cassandra doesn't
> try to migrate the directory structure. Also commitlog entries get skipped:
> "Skipped XXXXX mutations from unknown (probably removed) CF with id 1000"
> Without the unsuccessful step 4, Cassandra 1.1.9 loads and migrates the
> Keyspace correctly.
