stack updated HBASE-1790:
-------------------------
Attachment: testfilter.patch
Matus: Here is a TestFilter template that does the testing at the HRegion
interface. It might help you get going (I was afraid you'd try to figure how
best to test this and wander into the weeds and we'd never hear from you again).
Regards filters, the API and implementation changed in 0.20.0 so yeah, they
work for Dave and partially for others (such as Clint) but seems to be issues
here.
Thanks for helping out.

> Filters used in Scanning the table are not working correctly. For example a
> table with three rows:
> 1. rowkey = adminbackslash-nb0, desc:temp = "temp"
> 2. rowkey = adminbackslash-nb1, desc:temp = "temp"
> 3. rowkey = adminkleptoman, desc:temp = "temp"
> If I scan all rows in the table without filter I get all the rows as
> expected. But applying a simple prefixfilter with parameter "adminbackslash"
> will return only first row. I searched it down to HRegion::nextInternal
> method, which will not output one passed row before denied row(by filter).
