Hi, [~rajesh.balamohan].
How can I reproduce this? When I tested the following in Spark 1.6.3, 2.0.2, 2.1.1, 2.2.0, all passes.

{code}
scala> sql("create table x(a int) stored as orc")
res4: org.apache.spark.sql.DataFrame = [result: string]

scala> sql("create table y(a int) stored as orc")
res5: org.apache.spark.sql.DataFrame = [result: string]

scala> sql("select * from x, y where x.a=y.a").show
+---+---+
|  a|  a|
+---+---+
+---+---+
{code}
