Emmanuel Cecchet commented on SEQUOIA-1050:
-------------------------------------------

Hi Robert,

No, this does not affect existing recovery logs for distributed virtual 
database because this method is overridden in DistributedVirtualDatabase.
This method does not work in the non-distributed virtual database case anyway 
so there won't be any issues after upgrade. Actually, shutdown checkpoints are 
not used at all yet in the non-distributed case.

Cheers,
manu

> The code in VirtualDatabase.setShutdownCheckpoint does not generate unique 
> checkpoint names. Shutting down the controller for the second time on the 
> same controller will generate a duplicate entry exception in the recovery log.
> The method should use buildCheckpointName("shutdown") instead like in the 
> DistributedVirtualDatabase implementation.
