-----------------------------------------------------------------
So the final/approved workaround to be documented is:
Before performing an upgrade, please perform a "show keyspaces" to get the
current schema definitions. We recommend this as a best practice.
After the upgrade is complete, rerun the "show keyspaces" and check for any
drastic changes in the keyspace list.
Should there be keyspaces that disappear during the upgrade, please follow
these steps:
* In 1.1.1, show keyspaces to get schema definitions
* Upgrade to 1.1.5
* Do not run nodetool scrub
* Check keyspaces. If any are missing, recreate table definitions:
** Shutdown cluster
** rm data/system/system_schema*
** Restart cluster
** Run CREATE KEYSPACE + CREATE TABLE for missing keyspaces

> Here is how I got the problem to happen:
> 1. Get this zipped data directory (about 33Mb):
> scp cass@50.57.69.32:/home/cass/cassandra.zip ./ (password cass)
> 2. Unzip it in /var/lib/
> 3. clone the cassandra git repo
> 4. git checkout cassandra-1.1.1; ant jar;
> 5. bin/cassandra
> 6. Run cqlsh -3, then DESC COLUMNFAMILIES; Note the presence of Keyspace
> performance_tests
> 7. pkill -f cassandra; git checkout cassandra-1.1.5; ant realclean; ant jar;
> 8. bin/cassandra
> 9. Run cqlsh -3, then DESC COLUMNFAMILIES; Note that there is no
> performance_tests keyspace
