---------------------------------------
Summary: Replaying archived commitlogs isn't working
Key: CASSANDRA-6974
URL: https://issues.apache.org/jira/browse/CASSANDRA-6974
Project: Cassandra
Issue Type: Bug
Reporter: Ryan McGuire
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 currently relies on the fix for snapshots available in CASSANDRA-6965.)
