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

             Summary: Couldn't find corresponding Hive SerDe for data source provider org.apache.spark.sql.hive.orc.
                 Key: SPARK-22972
                 URL: https://issues.apache.org/jira/browse/SPARK-22972
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.2.1
            Reporter: xubo245



*There is error when running test code:*

{code:java}
  test("create orc table") {
    spark.sql(
      s"""CREATE TABLE normal_orc_as_source_hive
         |USING org.apache.spark.sql.hive.orc
         |OPTIONS (
         |  PATH '${new File(orcTableAsDir.getAbsolutePath).toURI}'
         |)
       """.stripMargin)
    val df = spark.sql("select * from normal_orc_as_source_hive")
    spark.sql("desc formatted normal_orc_as_source_hive").show()
  }
{code}

*warning:*

{code:java}
05:00:44.038 WARN org.apache.spark.sql.hive.test.TestHiveExternalCatalog: Couldn't find corresponding Hive SerDe for data source provider org.apache.spark.sql.hive.orc. Persisting data source table `default`.`normal_orc_as_source_hive` into Hive metastore in Spark SQL specific format, which is NOT compatible with Hive.

{code}

Root cause analysis:   
ORC related code is incorrect in HiveSerDe :

{code:java}

org.apache.spark.sql.internal.HiveSerDe#sourceToSerDe
{code}


{code:java}
  def sourceToSerDe(source: String): Option[HiveSerDe] = {
    val key = source.toLowerCase(Locale.ROOT) match {
      case s if s.startsWith("org.apache.spark.sql.parquet") => "parquet"
      case s if s.startsWith("org.apache.spark.sql.orc") => "orc"
      case s if s.equals("orcfile") => "orc"
      case s if s.equals("parquetfile") => "parquet"
      case s if s.equals("avrofile") => "avro"
      case s => s
    }
{code}

Solution:

change "org.apache.spark.sql.orc“  to  "org.apache.spark.sql.hive.orc"
