stack updated HBASE-1831:
-------------------------
Attachment: 1831.patch
Here is a bit of a start. It adds javadoc to the ipc interfaces about new
meaning of null. It then adds a new flag to the client-side nextScanner
method. It renames the method that checks for the end row in Scan.... Now to
work on server-side.
> Scanning API must be reworked to allow for fully functional Filters
> client-side

>
> Right now, a client replays part of the Filter locally by calling
> filterRowKey() and filterAllRemaining() to determine whether it should
> continue to the next region.
> A number of new filters rely on filterKeyValue() and other calls to alter
> state. It's also a false assumption that all rows/keys affecting a filter
> returning true for FAR will be seen client-side (what about those that failed
> the filter).
> This issue is about dealing with Filters properly from the client-side.
