idea用给scala打包出错Unsupported major.minor version 52.0

1.打包过程发现错误如下：

xception in thread "main" org.apache.spark.SparkException: Application application_1487576876020_5626 finished with failed status
	at org.apache.spark.deploy.yarn.Client.run(Client.scala:1167)
	at org.apache.spark.deploy.yarn.Client$.main(Client.scala:1213)

	at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:126)
	at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala)

　　首先快速在没有运行完前，查看log中报错：

Unsupported major.minor version 52.0

原因：是scala的jre和java的jdk不匹配，需要将idea中的scala版本有默认版本改为合适的对应版本，对应版本需要自己下载，下载镜像安装包，下载好后win下会自动配置环境变量，无需手动安装。
