pyspark --jars file1.jar,file2.jar 3. Create SparkSession with Jar dependency You can also add multiple jars to the driver and executor classpaths while creating SparkSession in PySpark as shown below. This takes the highest precedence over other approaches. # Create SparkSession spark = Spar...
We often need to create empty RDD in Spark, and empty RDD can be created in several ways, for example, with partition, without partition, and with pair RDD. In this article, we will see these with Scala, Java and Pyspark examples. Advertisements Spark sc.emptyRDD – Creates empty RDD wi...
