Summary: Bug with SingleColumnValueFilter and FamilyFilter
Key: HBASE-20151
URL: https://issues.apache.org/jira/browse/HBASE-20151
Project: HBase
Issue Type: Bug
Environment: MacOS 10.13.3
HBase 1.3.1
Reporter: Steven Sadowski
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}
