Group by and find first or last: refer to https://stackoverflow.com/a/35226857/1637673 For example, the elements of RDD1 are (Spark, Spark, Hadoop, Flink) and that of RDD2 are (Big data, Spark, Flink) so the resultant rdd1.union(rdd2) will have elements (Spark, Spark, Spark, Hadoop, Flink, Flink, Big data). Union() example: [php]val rdd1 = spark.sparkContext.parallelize(Seq((1,”jan”,2016),(3,”nov”,2014),(16,”feb”,2014))) PySpark sampling ( pyspark.sql.DataFrame.sample ()) is a mechanism to get random sample records from the dataset, this is helpful when you have a larger dataset and wanted to analyze/test a subset of the data for example 10% of the original file. Below is syntax of the sample () function.

This post has demonstrated how to pivot and resample time series in Pandas and Spark. The data used for this exercise is real measurements of energy production in Switzerland. The resampled data shows evidence of where nuclear power plant and renewable energy sources are located.

As a result, one common prerequisite for Times Series analytics is to take an initially raw input and transform it into discrete intervals, or to resample an input at one frequency into an input of a different frequency. The same basic techniques can be used for both use cases. Example – Create RDD from List. In this example, we will take a List of strings, and then create a Spark RDD from this list. RDDfromList.java. import java.util.Arrays; import java.util.List; import org.apache.spark.SparkConf; import org.apache.spark.api.java.JavaRDD; Spark provides the shell in two programming languages : Scala and Python.
