> The current count command in HBase shell is quite slow if the row size is very big (100+kB each). It would be helpful to provide some option to specify the column to count, which could give user a chance to reduce the data volume to scan.
> IMHO, only count the row key would be the ideal solution. Not sure how difficult to implement it.
