> 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. (state=,code=0)
