> When creating a snapshot, users can explicitly specify the TTL to be used. If
> no TTL is specified, then the SnapshotDescription is initially created with a
> TTL of -1 to indicate FOREVER.
> When the SnapshotDescription runs through SnapshotDescriptionUtils#validate,
> the TTL is checked to see if the default value of hbase.master.snapshot.ttl
> should be applied. The value from the config is only applied if the TTL == 0,
> but it should be -1.
> This has another nasty side-effect: any user who creates a snapshot and
> explicitly sets \{TTL => 0} will find that their snapshot gets its TTL from
> hbase.master.snapshot.TTL.
