          Read a CSV file as a dataframe



          val spark = SparkSession.builder().master("local[2]").appname("test").getOrCreate
          val df = spark.read.csv("path to csv")


          Now you can perform some operation to df and save as JSON



          df.write.json("output path")


          Hope this helps!

          • I tried to do that, but it is showing SparkException, IOException. And in error it is showing "Job is aborted while writing the rows". I don't know why. Can you help? I'm new to Spark, that is why finding it difficult to understand.
