Marcus Eriksson commented on CASSANDRA-7418:
--------------------------------------------

IIRC this happens if you try upgrading twice, maybe something (else) went wrong the first time?

I guess you can try removing the old snapshot (or just renaming the directory should be enough) and then trying to upgrade again

> I'm trying to migrate a cluster from 1.2.14 to 2.0.8. When starting up 2.0.8, I'm seeing the following error in the logs:
>  INFO 17:40:25,405 Snapshotting drillster, Account to pre-sstablemetamigration
> ERROR 17:40:25,407 Exception encountered during startup
> java.lang.RuntimeException: Tried to create duplicate hard link to /Users/tom/cassandra-data/data/drillster/Account/snapshots/pre-sstablemetamigration/drillster-Account-ic-65-Filter.db

> As a result, I can't start up 2.0.8, and switching back to 1.2.14 also doesn't work.
