> Just an idea I had. Might be useful for restore of a backup using the HLogs.
> This could an M/R (with a mapper per HLog file).
> The tool would get a timerange and a (set of) table(s). We'd pick the right 
> HLogs based on time before the M/R job is started and then have a mapper per 
> HLog file.
> The mapper would then go through the HLog, filter all WALEdits that didn't 
> fit into the time range or are not any of the tables and then uses 
> HFileOutputFormat to generate HFiles.
> Would need to indicate the splits we want, probably from a live table.
