Elias Ross created CASSANDRA-6298:
-------------------------------------

             Summary: Duplicate hard links; Cannot take snapshot (1.2)
                 Key: CASSANDRA-6298
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6298
             Project: Cassandra

          Components: Core
         Environment: Linux, multiple data directories, Java 6
            Reporter: Elias Ross


I've been seeing this. It could be related to CASSANDRA-6287 in some way. The version is 1.2.9.
