We have recently started seeing a lot of Schema Disagreement errors. We are using Cassandra 2.0.6 with Oracle Java 1.7. I went through the Cassandra FAQ and followed the below steps:
- nodetool disablethrift - nodetool disablegossip - nodetool drain - 'kill <pid>'. As per the documentation; the commit logs should have been flush; but that did not happen in our case. The commit logs were still there. So, I removed them manually to make sure there are no commit logs when cassandra start up( which was fine in our case as this data can always be replayed). I also deleted the schema* directory from the /data/system folder. Though when we started cassandra back up the issue started happening again. Any help would be appreciated Cheers! Gaurav
