Anoop Sam John commented on HBASE-20151:
----------------------------------------
Yes that was mentioned in my first comment. Thought we already fixed these
kind of issues in FL. This patch will solve the issue mentioned in the desc.
But this is not complete. SCVF is having latestVersionOnly flag and def to
true. If false it will check any version for the condition. In such a case
where the condition is becoming true for some older version, this return of
NEXT_COL will make an issue.

> Project: HBase
> Issue Type: Bug
> Environment: MacOS 10.13.3
> HBase 1.3.1

> 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}
