Apache Spark has a few big value propositions:
Apache Spark is one of the most popular projects in the Hadoop Ecosystem and is, in fact, the most actively developed open source project in Big data. And, it continues to attract more and more people every day.
It is popular not just among Data Scientists but also among Engineers, Developers and everybody else interested in Big Data. It is so popular that a lot of people believe it will grow to replace Map Reduce entirely.
It is popular because of three things: Simplicity, Performance, and Flexibility.
A few things why Spark is so popular :
With all these features, Spark has become the center of attraction for almost all of the Big Data developers and Data scientists. Though it has only been a few years, Spark has been evolving quickly and promises to be a sure contender for an industry standard in Big Data.
The advantages/benefits of Apache Spark are:-
Integration with Hadoop
Spark’s framework is built on top of the Hadoop Distributed File System (HDFS). So it’s advantageous for those who are familiar with Hadoop.
Faster
Spark also starts with the same concept of being able to run MapReduce jobs except that it first places the data into RDDs (Resilient Distributed Datasets). This data is now stored in memory so it’s more quickly accessible i.e. the same MapReduce jobs can run much faster because the data is accessed in memory.
Real-time stream processing
Every year, the real-time data being collected from various sources keeps shooting up exponentially. This is where processing and manipulating real-time data can help us. Spark helps us to analyze real-time data as and when it is collected.
Applications are fraud detection, electronic trading data, log processing in live streams (website logs), etc.
Graph Processing
Apart from Steam Processing, Spark can also be used for graph processing. From advertising to social data analysis, graph processing capture relationships in data between entities, say people and objects which are then are mapped out. This has led to recent advances in machine learning and data mining.
Powerful
Today companies manage two different systems to handle their data and hence end up building separate applications for it. One for streaming & storing real-time data. The other to manipulate and analyze this data. This means a lot of space and computational time. Spark gives us the flexibility to implement both batch and stream processing of data simultaneously, which allows organizations to simplify deployment, maintenance and application development.
Top Companies Using Spark
Including Spark support to Azure HDInsight (its cloud-hosted version of Hadoop).
To manage its SystemML machine learning algorithm construction, IBM uses Spark technology.
To run Spark apps developed in Scala, Java, and Python, Amazon uses Apache Spark.

Apache Spark is an open-source parallel processing framework for running large-scale data analytics applications across clustered computers. It can handle both batch and real-time analytics and data processing workloads.
Apache Spark can process data from a variety of data repositories, including the Hadoop Distributed File System (HDFS), NoSQL databases and relational data stores, such as Apache Hive. Spark supports in-memory processing to boost the performance of big data analytics applications, but it can also perform conventional disk-based processing when data sets are too large to fit into the available system memory.
The Spark Core engine uses the resilient distributed data set, or RDD, as its basic data type. The RDD is designed in such a way so as to hide much of the computational complexity from users. It aggregates data and partitions it across a server cluster, where it can then be computed and either moved to a different data store or run through an analytic model. The user doesn't have to define where specific files are sent or what computational resources are used to store or retrieve files.
In addition, Spark can handle more than the batch processing applications that MapReduce is limited to running.
Spark Libraries
The Spark Core engine functions partly as an application programming interface (API) layer and underpins a set of related tools for managing and analyzing data. Aside from the Spark Core processing engine, the Apache Spark API environment comes packaged with some libraries of code for use in data analytics applications. These libraries include:
Spark SQL
One of the most commonly used libraries, Spark SQL enables users to query data stored in disparate applications using the common SQL language.
Spark Streaming
This library enables users to build applications that analyze and present data in real time.
MLlib
A library of machine learning code that enables users to apply advanced statistical operations to data in their Spark cluster and to build applications around these analyses.
GraphX
A built-in library of algorithms for graph-parallel computation.
Apache Spark is a general purpose cluster-computing framework that can be deployed by multiple ways like streaming data, graph processing and Machine learning.

Apache Spark supports Java, Scala, Python APIs.
Scala is the language of the future and is the best language to learn for Apache Spark. Apache Spark is completely written in Scala.
Spark supports the Scala APIs as Spark is written completely in Scala. Hence Spark programs written in Scala might have some performance benefits. Since Scala is based on JVM, it is native for Hadoop and so seamlessly work with it. And, in almost all cases, it outperforms Python.
Scala is the most upcoming programming language. Scala combines object-oriented and functional programming in one concise, high-level language. Scala's static types help avoid bugs in complex applications, and its JVM and JavaScript runtimes let you build high-performance systems with easy access to huge ecosystems of libraries.

Machine Learning – Apache Spark is equipped with a scalable Machine Learning Library called MLlib that can perform advanced analytics such as clustering, classification, dimensionality reduction, etc. Some of the prominent analytics jobs like predictive analysis, customer segmentation, sentiment analysis, etc., make Spark an intelligent technology.
Fog computing – With the influx of big data concepts, IoT has acquired a prominent space for the invention of more advanced technologies. Based on the theory of connecting digital devices with the help of small sensors this technology deals with a humongous amount of data emanating from numerous mediums. This requires parallel processing which is certainly not possible on cloud computing. Therefore Fog computing which decentralizes the data and storage uses Spark streaming as a solution to this problem.
Event detection – The feature of Spark streaming allows the organization to keep track of rare and unusual behaviors for protecting the system. Institutions like financial institutions, security organizations, and health organizations use triggers to detect the potential risk.
Interactive analysis – Among the most notable features of Apache Spark is its ability to support interactive analysis. Unlike MapReduce that supports batch processing, Apache Spark processes data faster because of which it can process exploratory queries without sampling.
