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

             Summary: Cache's storage level is not respected when a table name is altered.
                 Key: SPARK-33786
                 URL: https://issues.apache.org/jira/browse/SPARK-33786
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Terry Kim


To repro:
{code:java}
        Seq(1 -> "a").toDF("i", "j").write.parquet(path.getCanonicalPath)
        sql(s"CREATE TABLE old USING parquet LOCATION '${path.toURI}'")
        sql("CACHE TABLE old OPTIONS('storageLevel' 'MEMORY_ONLY')")
        val oldStorageLevel = getStorageLevel("old")

        sql("ALTER TABLE old RENAME TO new")
        val newStorageLevel = getStorageLevel("new")
        assert(oldStorageLevel === newStorageLevel)
{code}
The assert fails:
Expected :StorageLevel(disk, memory, deserialized, 1 replicas)
Actual   :StorageLevel(memory, deserialized, 1 replicas)
