----------------------------------

             Summary: v2 ALTER TABLE .. DROP PARTITION does not refresh cached table
                 Key: SPARK-33987
                 URL: https://issues.apache.org/jira/browse/SPARK-33987
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Maxim Gekk


The test below portraits the issue:
{code:scala}
  test("SPARK-33950: refresh cache after partition dropping") {
    withNamespaceAndTable("ns", "tbl") { t =>
      sql(s"CREATE TABLE $t (id int, part int) $defaultUsing PARTITIONED BY (part)")
      sql(s"INSERT INTO $t PARTITION (part=0) SELECT 0")
      sql(s"INSERT INTO $t PARTITION (part=1) SELECT 1")
      assert(!spark.catalog.isCached(t))
      sql(s"CACHE TABLE $t")
      assert(spark.catalog.isCached(t))
      QueryTest.checkAnswer(sql(s"SELECT * FROM $t"), Seq(Row(0, 0), Row(1, 1)))
      sql(s"ALTER TABLE $t DROP PARTITION (part=0)")
      assert(spark.catalog.isCached(t))
      QueryTest.checkAnswer(sql(s"SELECT * FROM $t"), Seq(Row(1, 1)))
    }
  }
{code}
The last check fails:
{code}
== Results ==
!== Correct Answer - 1 ==   == Spark Answer - 2 ==
!struct<>                   struct<id:int,part:int>
![1,1]                      [0,0]
!                           [1,1]
{code}
