fixed spark setup : error : not found spark

error : not found spark

When I run my spark-shell, I encounter this error:
<console>:14: error: not found: value spark
       import spark.implicits._
              ^
<console>:14: error: not found: value spark
       import spark.sql
              ^


to resolve this 
give "chmod 777" basically permission for this folder to


 spark access "C:\tmp\hive"


Here is full command as flows:-
"C:\spark\Hadoop\bin\winutils.exe chmod 777 C:\tmp\hive"
