It was a simple reason.
```
test("broadcasted hash outer join operator selection") {
spark.sharedState.cacheManager.clearCache()
sql("CACHE TABLE testData")
sql("CACHE TABLE testData2")
Seq(
("SELECT * FROM testData LEFT JOIN testData2 ON key = a",
classOf[BroadcastHashJoinExec]),
("SELECT * FROM testData RIGHT JOIN testData2 ON key = a where key =
2",
classOf[BroadcastHashJoinExec]),
("SELECT * FROM testData right join testData2 ON key = a and key = 2",
classOf[BroadcastHashJoinExec])
).foreach(assertJoin)
sql("UNCACHE TABLE testData")
}
```
the cache table and uncache table do not match.
