问题
I install spark on windows, but it failed to run showing the error below:
<console>:16: error: not found: value sqlContext
import sqlContext.implicits._
^
<console>:16: error: not found: value sqlContext
import sqlContext.sql
^
I tried the links below but any one of them resolves the issue: 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
The complete log of spark execution is below:

回答1:
I had exactly the same issue and went through a number of possible solutions as explained in the links you posted, but nothing worked at the time. By running the spark-shell command, it creates the tmp\hive directory in C: and eventually found out that there was an issue with the permissions. I have made sure that my HADOOP_HOME was correctly set up and it contained the \bin\winutils.exe, then simply moved tmp\hive under %HADOOP_HOME%\bin and restarted the command prompt. This finally resolved the issue, but do remember to run the cmd as an administrator. Hope this helps, I.
回答2:
I was facing the same issue, after investigation i observed there was the compatibility issue between spark version and winutils.exe of hadoop-2.x.x.
After experiment i suggest you to use hadoop-2.7.1 winutils.exe with spark-2.2.0-bin-hadoop2.7 version and hadoop-2.6.0 winutils.exe with spark-1.6.0-bin-hadoop2.6 version and set below environment variables
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;
Create C:\tmp\hive diroctory and grant access permission using below command
C:\Hadoop\winutils-master\hadoop-2.7.1\bin>winutils.exe chmod -R 777 C:\tmp\hive
Remove metastore_db directory from below path if exist.
C:\Users\<User_Name>\metastore_db
Use below command to start spark shell
C:>spark-shell
回答3:
I too had similar issue (import spark.implicits._ not found) for windows 10.
As suggested in the post
I set
1. HADOOP_HOME (%HADOOP_HOME%/bin/winutils.exe - should exist)
2. %HADOOP_HOME%/bin/winutils.exe chmod -R 777 F:\tmp\hive (spark-2.1.1 and winutils(hadoop 2.7.1) on same F: drive, in my case)
