Cheney Sun commented on HBASE-9086:

@Lars, no, that's not what I expect. the new patch was uploaded, and pick up the Jean-Marc's
suggestion by adding FirstKeyOnlyFilter and KeyOnlyFilter to a Filter list.

> 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
