Pavel Yaskevich updated CASSANDRA-4219:
---------------------------------------
Attachment: CASSANDRA-4219.patch
The problem was that when KS/CF is deleted row in the system table is marked
for delete and all of it's columns are moved, so when it's re-created columns
are added but row stays marked for delete, we need to check if given KS/CF
doesn't have attributes in it's system table and if it's marked for delete all
together, when we do schema version re-generate or load.

> Hi,
> I'm doing testing and wanted to drop a keyspace (with a column family) to
> re-add it with a different strategy. So I ran in cqlsh:
> DROP KEYSPACE PlayLog;
> CREATE KEYSPACE PlayLog WITH strategy_class = 'SimpleStrategy'
> AND strategy_options:replication_factor = 2;
> And everything seemed to be fine. I ran some inserts, which also seemed to go
> fine, but then selecting them gave me:
> cqlsh:PlayLog> select count(*) from playlog;
> TSocket read 0 bytes
> I wasn't sure what was wrong, so I tried dropping and creating again, and now
> when I try to create I get:
> cqlsh> CREATE KEYSPACE PlayLog WITH strategy_class = 'SimpleStrategy'
> ... AND strategy_options:replication_factor = 2;
> TSocket read 0 bytes
> And the keyspace doesn't get created. In the log it shows:
> ERROR [Thrift:4] 2012-05-03 18:23:05,124 CustomTThreadPoolServer.java (line
> 204) Error occurred during processing of message.
