[报错]Exception: Found duplicate column(s) in the data schema: `value`；

    val value_path="file:///Users/kelisiduofu/Desktop/UIS/value1"
    val conf=new SparkConf().setAppName("UIS_TMP").setMaster("local[*]")
    val spark=SparkSession.builder().config(conf).getOrCreate()
    val frame1=spark.read.json(value_path)
    frame1.createTempView("t1")
    spark.sql("select * from t1").show()

检查json串，发现有两个value

设置大小写敏感即可

    val value_path="file:///Users/kelisiduofu/Desktop/UIS/value1"
    val conf=new SparkConf().setAppName("UIS_TMP").setMaster("local[*]")
    val spark=SparkSession.builder().config(conf).getOrCreate()
    spark.sql("set spark.sql.caseSensitive=true")---这里
    val frame1=spark.read.json(value_path)
    frame1.createTempView("t1")
    spark.sql("select * from t1").show()
