Question

我有一个带有火花1.6设置的hortonwork沙箱2.4。然后我使用hdp spark jar和scala 2.10.5在windows中创建Intellij spark开发环境。因此，我的窗口和hdp环境之间匹配spark和scala版本，如here所示。我的Intellij开发环境与本地的Master一起工作。然后我尝试使用

连接Windows中的hdp

val sparkConf = new SparkConf()
      .setAppName("spark-word-count")
      .setMaster("spark://10.33.241.160:7077")

我得到以下错误信息，并且无法解决问题。请帮忙！

事实证明，每次服务器重启时，我都需要将hortonworks Spark设置为主服务器。然后使用我的intellij dev环境连接hdp作为slave。只需在hdp中运行./sbin/start-master.sh作为此link。

Intellij连接hortonwork spark远程失败
