title: Apache spark error: not found: value sqlContext
body: <p>I am trying to set up spark in Windows 10. Initially, I faced <a href="https://stackoverflow.com/questions/36720067/spark-fail-in-windows-console16-error-not-found-value-sqlcontext">this error</a> while starting and the solution in the link helped. Now I am still not able to run <code>import sqlContext.sql</code> as it still throws me an error</p>
