Spark SQL on ORC files doesn't return correct Schema (Column names)

Question

I have a directory containing ORC files. I am creating a DataFrame using the below code

var data = sqlContext.sql(\"SELECT * FROM orc.`/directory/containing/         


        

Answer 1

We can use:

val df = hiveContext.read.table("tableName")

Your df.schema or df.columns will give actual column names.
