API signature wise I am okey Lars. Passing in Scan attributes, I was in 2 minds all the time..:)

Yes Lars you can do that if you like  :)

bq.Eventually, since we made it so general now, I can see this as an official API in HTable...
But let's do that in an another jira (if others agree).

> We can provide an end point implementation for doing a bulk deletion of rows(based on
a scan) at the server side. This can reduce the time taken for such an operation as right
now it need to do a scan to client and issue delete(s) using rowkeys.
