>
> When a region server's lease times out, the master immediately begins trying
> to split the server's log file. There have been cases where a region server
> was just a little late reporting to the master and the master had already
> started trying to reclaim the server's log, even though the server was still
> writing to it.
> There needs to be some kind of "grace period" in which, if the region server
> reports in, the master re-instates the server. If the "grace period" expires,
> then the master should start processing the server's log.
