------------------------------
Summary: Join between 2 hbase/M7 tables using the dot notation
fails
Key: DRILL-1277
URL: https://issues.apache.org/jira/browse/DRILL-1277
Project: Apache Drill
Issue Type: Bug
Components: Storage - HBase
Reporter: Krystal
git.commit.id.abbrev=98b208e
I have the following join query between 2 hbase tables that runs successfully:
select cast(student.onecf['name'] as varchar(35)) name,
cast(student.twocf['age'] as integer) age, cast(student.threecf['gpa'] as
decimal(4,2)) gpa, cast(voter.twocf['registration'] as varchar(20))
registration from student join voter on (student.onecf['name'] =
voter.onecf['name']);
I converted the above query to use the dot notation:
select cast(student.onecf.name as varchar(35)) name, cast(student.twocf.age as
integer) age, cast(student.threecf.gpa as decimal(4,2)) gpa,
cast(voter.twocf.registration as varchar(20)) registration from student join
voter on (student.onecf.name = voter.onecf.name);
However this query failed with the following error message:
Query failed: Failure while parsing sql. java.lang.NullPointerException
[90df667c-9041-45a2-96c2-8400a6a91f91]
Error: exception while executing query: Failure while trying to get next result
