'saveAsOrcFile' error in tutorial lab-4 on Spark

[#1]

in the sandbox tutorial Lab-4 on Spark, when running this statement:

risk_factor_spark.saveAsOrcFile("risk_factor_spark")

it gives me the following error:

error: value saveAsOrcFile is not a member of org.apache.spark.sql.DataFrame

I have done the 'import org.apache.spark.sql.hive.orc._' earlier in the lab. Also tried capital '..ORC..'. And I am using the built-in web client for the SSH client.

Any suggestions?

. @David Andreae If you are using Spark >= 1.4 try the following command

risk_factor_spark.write.format("orc").save("risk_factor_spark")

This helped me - thank you.
