Benedict edited comment on CASSANDRA-6974 at 4/21/14 11:11 PM:
---------------------------------------------------------------

[~yukim]: seems there is the alternative of being able to create a CF with an 
explicit UUID?

We probably could treat this differently on replay if we wanted, though. Not 
sure if it's actually the correct behaviour since CFs could be dropped and 
recreated deliberately across restores, and we wouldn't be honouring that 
transition with that change.

> I have a test for restoring archived commitlogs, which is not working in 2.1 
> HEAD.  My commitlogs consist of 30,000 inserts, but system.log indicates 
> there were only 2 mutations replayed:
> {code}
> INFO  [main] 2014-04-02 11:49:54,173 CommitLog.java:115 - Log replay 
> complete, 2 replayed mutations
> {code}
> There are several warnings in the logs about bad headers and invalid CRCs: 
> {code}
> WARN  [main] 2014-04-02 11:49:54,156 CommitLogReplayer.java:138 - Encountered 
> bad header at position 0 of commit log /tmp/dtest
> -mZIlPE/test/node1/commitlogs/CommitLog-4-1396453793570.log, with invalid 
> CRC. The end of segment marker should be zero.
> {code}
> compare that to the same test run on 2.0, where it replayed many more 
> mutations:
> {code}
>  INFO [main] 2014-04-02 11:49:04,673 CommitLog.java (line 132) Log replay 
> complete, 35960 replayed mutations
> {code}
> I'll attach the system logs for reference.
> [Here is the dtest to reproduce 
> this|https://github.com/riptano/cassandra-dtest/blob/master/snapshot_test.py#L75]
>  - (This currently relies on the fix for snapshots available in 
> CASSANDRA-6965.)
