> 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 batch.
