Lars Hofhansl commented on HBASE-10485:
---------------------------------------

[~stack], I assume you want that in 0.96. I'll commit to 0.94 and 0.96 unless I hear an objection
from you.

> Niels reported an issue under the thread 'Trouble writing custom filter for use in FilterList'
where his custom filter used in FilterList along with PrefixFilter produced an unexpected
results.
> His test can be found here:
> https://github.com/nielsbasjes/HBase-filter-problem
> This is due to PrefixFilter#filterKeyValue() using FilterBase#filterKeyValue() which
returns ReturnCode.INCLUDE
> When FilterList.Operator.MUST_PASS_ONE is specified, FilterList#filterKeyValue() would
return ReturnCode.INCLUDE even when row key prefix doesn't match meanwhile the other filter's
filterKeyValue() returns ReturnCode.NEXT_COL
