> 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
