> Currently the HLog archiving thread adds another timestamp to ensure the file
> names are "unique". This is ugly and makes it harder to track the HLogs
> movements from outside (like replication). Instead we could use a UUID as the
> file name.
> I was discussing with Stack the need of keeping a timestamp in the file
> name... I think we can't get rid of it since we need to read the HLogs in
> sequence when splitting.
