using Scan(startRow,stopRow) will cause you to iterate the entire table
-----------------------------------------------------------------------
Key: HBASE-1566
URL: https://issues.apache.org/jira/browse/HBASE-1566
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.20.0
Reporter: ryan rawson
Priority: Blocker
Fix For: 0.20.0
Right now the only way for the client scanner to know that we are at the 'end'
of a scan is to client-side-wise use the filter to figure this out.
This is not easy to fix because the server is unable to indicate the difference
between 'done with this region', and 'you're at the end of your scan'. In both
cases we return 0 results, and the client can't figure out what it means.
Right now the best solution is to use filters, which is tricky since there is
no StopRowFilter because that functionality is built in :-)
We might have to hack the 'stop row' functionality as a filter until we can
improve the client-server API/RPC.
