1. Objective<\/h2>\n

Here you will learn some of the important Apache Spark Terminologies and Apache Spark Key terms that are being used in the\u00a0Spark industry. It will help you in learning what is Apache Spark<\/a>, what does spark engine do, partition in Apache Spark, what does MLlib do, worker node in Spark, Spark SQL<\/a> and Pair RDD<\/a> definition, what is lazy evaluation in Spark, Spark Driver and Action in Spark.<\/p>\n

Apache Spark Terminologies and Concepts You Must Know<\/p><\/div>\n

2. Introduction to Apache Spark\u00a0Terminologies<\/h2>\n

Before we start with testing the knowledge, let us revise our Spark key concepts<\/a> and understand how Apache Spark is better than<\/a>\u00a0Hadoop MapReduce<\/a> in terms of usage and performance.
