Subject [jira] [Created] (CASSANDRA-4752) Drop keyspace causes schema disagreement
Date Wed, 03 Oct 2012 10:40:07 GMT
Sam Tunnicliffe created CASSANDRA-4752:
------------------------------------------

             Summary: Drop keyspace causes schema disagreement 
                 Key: CASSANDRA-4752
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4752
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 1.1.6
            Reporter: Sam Tunnicliffe


The fix for CASSANDRA-4698 introduced a bug whereby when drop keyspace is issued a schema
disagreement immediately occurs. This seems to be because the 

{code}
	ColumnFamily cf = ColumnFamily.create(modification.getValue().metadata());
{code}

in {{RowMutation.deserializeFixingTimestamps}} does not preserve deletion info for the cf
in the modification. In most cases, this doesn't cause a problem, but for a drop keyspace
modification, there are no columns in the cf, so the deletion info is effectively lost leading
to an incorrect digest being created and ultimately a schema disagreement.

Replacing the {{create}} with {{cloneMeShallow}} does preserve the deletion info and avoids
the schema disagreement issue.
