Review comment:
Since this isn't using any of the planning test functions please extend
ClusterTest instead and use the ClientFixture to run the queries. We are trying
to move all the integration tests to using ClusterFixture and ClientFixture
instead of the now deprecated BaseTestQuery and its child classes.

> Create two views using following statements.
> {code}
> create view v1 as select cast(greeting as int) f from
> dfs.`/home/mapr/data/json/temp.json`;
> create view v2 as select cast(greeting as int) f from
> dfs.`/home/mapr/data/json/temp.json`;
> {code}
> Executing the following join query produces a stack overflow during the
> planning phase.
> {code}
> select t1.f from dfs.tmp.v1 as t inner join dfs.tmp.v2 as t1 on cast(t.f as
> int) = cast(t1.f as int) and cast(t.f as int) = 10 and cast(t1.f as int) = 10;
> {code}
