----------------------------------
Summary: Incorrect results when referencing same Accumulo table
multiple times in one query
Key: HIVE-18802
URL: https://issues.apache.org/jira/browse/HIVE-18802
Project: Hive
Issue Type: Bug
Affects Versions: 3.0.0
Reporter: Anthony Hsu
While investigating HIVE-18695, I noticed incorrect results returned by the
following Accumulo query:
{code:java}
DROP TABLE accumulo_test;
CREATE TABLE accumulo_test(key int, value int)
STORED BY 'org.apache.hadoop.hive.accumulo.AccumuloStorageHandler'
WITH SERDEPROPERTIES ("accumulo.columns.mapping" = ":rowID,cf:string")
TBLPROPERTIES ("accumulo.table.name" = "accumulo_table_0");
INSERT OVERWRITE TABLE accumulo_test VALUES (0,0), (1,1), (2,2), (3,3);
SELECT * from accumulo_test where key == 1 union all select * from
accumulo_test where key == 2;{code}
The expected output is
{code:java}
1 1
2 2{code}
but the actual output is
{code:java}
1 0
1 1
1 2
1 3
2 0
2 1
2 2
2 3
{code}
