[jira] [Created] (SPARK-19484) continue work to create a table with an empty schema

Song Jun created SPARK-19484:
--------------------------------

             Summary: continue work to create a table with an empty schema
                 Key: SPARK-19484
                 URL: https://issues.apache.org/jira/browse/SPARK-19484
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.2.0
            Reporter: Song Jun
            Priority: Minor


after SPARK-19279, we could not create a Hive table with an empty schema,
we should tighten up the condition when create a hive table in 

https://github.com/apache/spark/blob/master/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/HiveClientImpl.scala#L835

That is if a CatalogTable t has an empty schema, and (there is no `spark.sql.schema.numParts` or its value is 0), we should not add a default `col` schema, if we did, a table with an empty schema will be created, that is not we expected.
