Apache Spark 1.12.2 is an open-source, distributed computing framework that may course of huge quantities of information in parallel. It provides a variety of options, making it appropriate for a wide range of purposes, together with knowledge analytics, machine studying, and graph processing. This information will offer you the important steps to get began with Spark 1.12.2, from set up to operating your first program.
Firstly, you will want to put in Spark 1.12.2 in your system. The set up course of is easy and well-documented. As soon as Spark is put in, you can begin writing and operating Spark applications. Spark applications will be written in a wide range of languages, together with Scala, Java, Python, and R. For this information, we are going to use Scala as the instance language.
To write down a Spark program, you will want to make use of the Spark API. The Spark API supplies a set of courses and strategies that help you create and manipulate Spark dataframes and datasets. Dataframes are distributed collections of information which might be saved in reminiscence. Datasets are distributed collections of information which might be saved on disk. Each dataframes and datasets can be utilized to carry out a wide range of operations, together with filtering, sorting, and aggregation.
