我在Windows上安装了spark，但是无法运行显示以下错误：
<console>:16: error: not found: value sqlContext
import sqlContext.implicits._
^
<console>:16: error: not found: value sqlContext
import sqlContext.sql
^
我尝试了下面的链接，但其中任何一个都解决了这个问题： How to start Spark applications on Windows (aka Why Spark fails with NullPointerException)?
Apache Spark error while start
error when starting the spark shell
error: not found: value sqlContext
火花执行的完整日志如下：

我遇到了完全相同的问题，并按照您发布的链接中的说明进行了一些可能的解决方案，但当时没有任何效果。通过运行spark-shell命令，它在C：中创建了tmp \ hive目录，并最终发现权限存在问题。我已确保我的HADOOP_HOME已正确设置并且包含\ bin \ winutils.exe，然后只需在％HADOOP_HOME％\ bin下移动tmp \ hive并重新启动命令提示符。这最终解决了这个问题，但请记住以管理员身份运行cmd。希望这有帮助，我。

我遇到了同样的问题，经过调查我发现 {{>> spark version 与 winutils.exe 之间存在兼容性问题{3}}
经过实验，我建议你使用 hadoop-2.7.1 winutils.exe 和 spark-2.2.0-bin-hadoop2.7 版本和 hadoop带有 spark-1.6.0-bin-hadoop2.6 版本的-2.6.0 winutils.exe 并设置如下环境变量
SCALA_HOME : C:\Program Files (x86)\scala2.11.7;
JAVA_HOME : C:\Program Files\Java\jdk1.8.0_51
HADOOP_HOME : C:\Hadoop\winutils-master\hadoop-2.7.1
SPARK_HOME : C:\Hadoop\spark-2.2.0-bin-hadoop2.7
PATH : %JAVA_HOME%\bin;%SCALA_HOME%\bin;%HADOOP_HOME%\bin;%SPARK_HOME%\bin;
使用以下命令创建 C：\ tmp \ hive diroctory并授予访问权限
C:\Hadoop\winutils-master\hadoop-2.7.1\bin>winutils.exe chmod -R 777 C:\tmp\hive
如果存在，请从下面的路径中删除 metastore_db 目录。
C:\Users\<User_Name>\metastore_db
使用以下命令启动spark shell
C:>spark-shell

我也有类似的问题（导入spark.implicits._ not found）for windows 10
正如帖子中所建议的那样
我设定了
1. HADOOP_HOME （％HADOOP_HOME％/ bin / winutils.exe - 应该存在）
2. ％HADOOP_HOME％/ bin / winutils.exe chmod -R 777 F：\ tmp \ hive （spark-2.1.1和winutils（hadoop 2.7.1）在同一个F：驱动器上，在我的案件）
