Apache Spark 1.12.2 is an open-source, distributed computing framework that may course of large quantities of information in parallel. It gives 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 give you the important steps to get began with Spark 1.12.2, from set up to operating your first program.
Firstly, you’ll need to put in Spark 1.12.2 in your system. The set up course of is simple and well-documented. As soon as Spark is put in, you can begin writing and operating Spark packages. Spark packages may 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 put in writing a Spark program, you’ll need 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 are saved in reminiscence. Datasets are distributed collections of information which are saved on disk. Each dataframes and datasets can be utilized to carry out a wide range of operations, together with filtering, sorting, and aggregation.
