星火SQL读取JSON文件从HDFS失败

我这样的代码：星火SQL读取JSON文件从HDFS失败

val sqlContext = new org.apache.spark.sql.hive.HiveContext(sc) 
import sqlContext.implicits._ 
val customers = sqlContext.read.json("jsonfilepath")

在火花外壳出现的错误，我不明白这一点：？

错误信息清楚地说，你需要改变你的数据库 –

为什么使用HiveContext来读取json数据？请使用SOLContext代替。

val sqlContext = new org.apache.spark.sql.SQLContext(sc) 
import sqlContext.implicits._ 
val customers = sqlContext.read.json("jsonfilepath")
