> There are some disadvantages to large cell, such as can't be cached or cause
> memory fragmentation, but currently user can't easily to find them out.
> My proposal is save len and key of the biggest cell into fileinfo of hfile,
> and shown on web ui, including two places.
> 1: Add "Len Of Biggest Cell" into main page of regionServer, in here we can
> find out which regions has large cell by sorting.
> 2: Add "Len Of Biggest Cell" and "Key Of Biggest Cell" into region page, in
> here we can find out the exactly key and the hfile.
