The original reason of this PR was a simple .
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.
Later, we found that replace _uncache table_ with
_spark.sharedState.cacheManager.clearCache()_
Finally, it's now modified it.
