Description

The test below portraits the issue:

  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)))
    }
  }

The last check fails:
