> 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`;

> 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;
