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"
