spark sql data source --hive

The idea is to use editor

spark sql step of reading data from the hive: hive jar package 1 is introduced

                                                          2. The hive-site.xml put under resource

　　　　　　　　　　　　　　　　3.spark sql statement in support of the hive

Case:

def main(args: Array[String]): Unit = {
  val spark: SparkSession = SparkSession
    .builder()
    .appName(s"${this.getClass.getSimpleName}")
 .master("local[*]")
 .enableHiveSupport()
 .getOrCreate()

 //指明要使用的数据库
 spark.sql("use zhangqi")
 spark.sql("select * from monitor_camera_info limit 10").show()
 //关闭资源
 spark.close()
