无法通过Jupyter导入sqlContext.implicits._没有错误 [英] Can't import sqlContext.implicits._ without an error through Jupyter

问题描述

当我尝试在Jupyter笔记本上使用import sqlContext.implicits._时，出现以下错误:

When I try to use the import sqlContext.implicits._ on my Jupyter notebook, I get the following error:

Name: Compile Error
Message: <console>:25: error: stable identifier required, but $iwC.this.$VAL10.sqlContext.implicits found.
       import sqlContext.implicits._
                         ^

我已经在本地尝试过了，并且可以使用，但是在我的Jupyter Notebook服务器(托管在ec2上)上使用它时，此功能无法正常使用.我曾尝试导入与此相关的其他库，但不幸的是无法使其正常工作.

I've tried this locally and it works, but this does not properly function when using it on my Jupyter Notebook server (which is hosted on ec2). I have tried importing different libraries involving that, but unfortunately can not get it to function.

推荐答案

您需要像这样实例化sqlContext:

You need to instantiate a sqlContext like so:

val sqlC = new org.apache.spark.sql.SQLContext(sc)
import sqlC.implicits._

您应该已经看到此错误:

You should have seen this error:

需要稳定的标识符

stable identifier required
