ScrapCodes opened a new pull request #24657: [MINOR][DOCS] Fix Spark hive example.
URL: https://github.com/apache/spark/pull/24657
 
 
   ## What changes were proposed in this pull request?
   
   Documentation has an error, https://spark.apache.org/docs/latest/sql-data-sources-hive-tables.html#hive-tables.
   
   The example:
   ```scala
   scala> val dataDir = "/tmp/parquet_data"
   dataDir: String = /tmp/parquet_data
   
   scala> spark.range(10).write.parquet(dataDir)
                                                                                   
   scala> sql(s"CREATE EXTERNAL TABLE hive_ints(key int) STORED AS PARQUET LOCATION '$dataDir'")
   res6: org.apache.spark.sql.DataFrame = []
   
   scala> sql("SELECT * FROM hive_ints").show()

   Range does not emit `key`, but `id` instead.
