In this free Apache Spark Tutorial you will be introduced to Spark analytics, Spark streaming, RDD, Spark on cluster, Spark shell and actions. You will learn about Spark practical use cases. Apache Spark continues to gain momentum in today’s big data analytics landscape. Although a relatively newer entry to the realm, Apache Spark has earned immense popularity among enterprises and data Analysts within a short period. Apache Spark is one of the most active open source big data projects. The reason behind is its versatility and diversity of use.
Some of the key features that make Spark a strong big data engine are:
- Equipped with MLlib library for machine learning algorithms
- Good for Java and Scala developers as Spark imitates Scala’s collection API and functional style
- Single library can perform SQL, graph analytics and streaming.

Spark is admired for many reasons by developers and analysts to quickly query, analyze and transform data at scale. In simple words, you can call Spark a competent alternative to Hadoop, with its characteristics, strengths and limitations. Spark runs in-memory to process data with speed and sophistication than the other complement approaches like Hadoop MapReduce. It can handle several terabytes of data at one time and perform efficient processing.
Spark versus Hadoop MapReduce
Despite having the similar functionality, there is much difference between these two technologies. Let’s have a quick look into this comparative analysis:
|Processing Location||In-memory||Persists on disk after map and reduce functions|
|Ease of use||Easy as based on Scala||Difficult as based on Java|
|Speed||Up to 100 times faster than Hadoop MapReduce||Slower|
|Computation||Iterative computation possible||single computation possible|
|Task Scheduling||Schedules tasks itself||Requires external schedulers.|
One of the excellent benefits of using Spark is that it is often used in Hadoop’s data storage model, i.e. HDFS and can well integrate with other big data frameworks like HBase, MongoDB, Cassandra. It is one of the best big data choices to learn and apply machine learning algorithms in real-time. It has the ability to run repeated queries on large databases and potentially deal with them.
Knowing the extensively excellent future growth and rapid adoption of Apache Spark in today’s business world, we have designed this Spark tutorial to educate the mass programmers on interactive and expeditious framework.
