星火SQL讀取JSON文件從HDFS失敗

我這樣的代碼：星火SQL讀取JSON文件從HDFS失敗

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

在火花外殼出現的錯誤，我不明白這一點：？

錯誤信息清楚地說，你需要改變你的數據庫 –

爲什麼使用HiveContext來讀取json數據？請使用SOLContext代替。

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

的權限，我想保存數據蜂巢使用HiveContext，SQLContext對我的作品 – shaojie
