Scanning process does not start parallely on all regions.  Once a start row
is specified with the scan, the corresponding region server is picked up
and on that region server,
the scan starts from that region which holds the start row and the scan
proceeds till it finds the stop row. The stop row can be any of the regions
in the same region server, in the exact increasing byte order.
