Ted Yu commented on HBASE-6942:
-------------------------------

In patch v5, rowBatchSize isn't used in the following call:
{code}
+          hasMore = scanner.next(results);

{code}
+    byte[] row = deleteRow.get(0).getRow();
{code}
Is this intended ?

> 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.
