Hello Doug,
First of all thanks for taking time to reply.
As per my knowledge goes below two lines take the rowkey as a parameter for
representing start and end.
scan.setStartRow( Bytes.toBytes("row")); // start key is
inclusive
scan.setStopRow( Bytes.toBytes("row" + (char)0)); // stop key is exclusive
But,
In my case irrespective of rowkey I need 100 rows always. If I go with this
concept if 5 rows are deleted in between 1 to 100 then it will give me 95
but not 100.
But for me always I need 100 (I mean rowCount whatever I pass) rows.
And as after usage there may be deletions of rows or adding and all on DB, I
can't keep track of rows for this paging..
Paging needs a fixed number of rows in each page always.

Hi there,
Pretty similar approach with Hbase. See the Scan class.
