> When a region server dies, the master reallocates all the regions it was
> serving to other region servers. In order for the regions to be recovered
> properly, the log from the old region server must be split up into chunks
> that contain only the commits for a single region.
> Ideally, if a region server is assigned more than one of the old servers
> regions, the log for that server would contain all the commits for all the
> regions it has been assigned.
