> In looking at HBASE-3421 I wrote a small tool to scan an HFile and produce some basic statistics about it:
> - min/mean/max key size, value size (uncompressed)
> - min/mean/max number of columns per row (uncompressed)
> - min/mean/max number of bytes per row (uncompressed)
> - the key of the largest row
