Apache Spark 1.12.2 is an open-source, distributed computing framework that may course of huge quantities of knowledge in parallel. It gives a variety of options, making it appropriate for quite a lot of functions, 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 working your first program.
Firstly, you will have 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 working Spark packages. Spark packages could be written in quite a lot of languages, together with Scala, Java, Python, and R. For this information, we’ll use Scala as the instance language.
To put in writing a Spark program, you will have to make use of the Spark API. The Spark API offers a set of lessons and strategies that permit you to create and manipulate Spark dataframes and datasets. Dataframes are distributed collections of knowledge which might be saved in reminiscence. Datasets are distributed collections of knowledge which might be saved on disk. Each dataframes and datasets can be utilized to carry out quite a lot of operations, together with filtering, sorting, and aggregation.
