Zheng Hu commented on HBASE-20151:
----------------------------------
Now I am worried that if the implementation of filterRow is related to the
cells in entire row, this bug may exist, but if the implementation of filterRow
is only related to rowkey, then there is no such problem. Because the former
one may need the FilterList to visit all cells in an row (if not, filterRow
will filter out the entire row), and obviously we can't guarantee this now.

> When running the following queries, the result is sometimes return correctly
> and other times incorrectly based on the qualifier queried.
> Setup:
> {code:java}
> create 'test', 'a', 'b'
> test = get_table 'test'
> test.put '1', 'a:1', nil
> test.put '1', 'a:10', nil
> test.put '1', 'b:2', nil
> {code}
>
> This query works fine when the SCVF's qualifier has length 1 (i.e. '1') :
> {code:java}
> test.scan({ FILTER => "(
> SingleColumnValueFilter('a','1',=,'binary:',true,true) AND
> FamilyFilter(=,'binary:b') )"})
> ROW COLUMN+CELL
> 1 column=b:2,
> timestamp=1520455888059, value=
> 1 row(s) in 0.0060 seconds
> {code}
>
> The query should return the same result when passed a qualifier of length 2
> (i.e. '10') :
> {code:java}
> test.scan({ FILTER => "(
> SingleColumnValueFilter('a','10',=,'binary:',true,true) AND
> FamilyFilter(=,'binary:b') )"})
> ROW COLUMN+CELL
> 0 row(s) in 0.0110 seconds
> {code}
> However, in this case, it does not return any row (expected result would be
> to return the same result as the first query).
>
> Removing the family filter while the qualifier is '10' yields expected
> results:
> {code:java}
> test.scan({ FILTER => "(
> SingleColumnValueFilter('a','10',=,'binary:',true,true) )"})
> ROW COLUMN+CELL
> 1 column=a:1,
> timestamp=1520455887954, value=
> 1 column=a:10,
> timestamp=1520455888024, value=
> 1 column=b:2,
> timestamp=1520455888059, value=
> 1 row(s) in 0.0140 seconds
> {code}
