Stefan Egli commented on OAK-3435:
----------------------------------

for logging/debug purpose that could be very useful yes. for the 'discovery lite' descriptor that information would not be needed. but good to know it is there!

> In order to make debugging easier, we should:
> - log exceptions that occur while updating the cluster node info entries
> - when we mark an entry as being recovered, record which cluster node is running the recovery
> - avoid the conditional race condition mentioned in the code comment for acquireRecoveryLock
> - improve logging for cluster node infos that match the current instance id but for some reason will not be recovered
