While DB2, ORACLE etc support a join expressed as follows, SPARK SQL does not.
Not supported
select * from
cert.tsint tsint inner join cert.tint tint inner join cert.tbint tbint
on tbint.rnum = tint.rnum
on tint.rnum = tsint.rnum
versus written as shown
select * from
cert.tsint tsint inner join cert.tint tint on tsint.rnum = tint.rnum inner
join cert.tbint tbint on tint.rnum = tbint.rnum
