What is Apache Spark?
Apache Spark is a collection platform designed to be general purpose and fast. Spark is created to be highly accessible, offering simple APIs in Scala, SQL, Python, and Java and rich built-in libraries.
Apache Spark is developed as the next generation big data processing engine, and is being applied throughout the industry faster than ever. Apache Spark improves over Hadoop Map Reduce, which helped ignite the big data revolution, in several key dimensions: it is faster, much easier to use due to its rich API’s and its goes far above batch applications to support a variety of including interactive queries, workloads, machine learning, graph processing, and streaming.

Apache Spark is an exciting new technology that is rapidly superseding Hadoop as the preferred Big Data processing platform. Its unique design, which allows for keeping large parts of data in memory, offers tremendous performance improvements. Spark programs can be even 100 times faster than their Hadoop counterparts. Spark’s elegant API and runtime architecture allow you to write distributed programs in a manner similar to writing the local ones, using functional programming methods, which are very appropriate for data processing. By supporting Python, Java and Scala, Spark is open to a wide range of users: to the science community traditionally favoring Python, to the still widespread Java community and to people using the ever more popular Scala, offering functional programming on the JVM. Finally, Spark combines MapReduce-like capabilities for batch programming, real-time data processing functions, SQL-like handling of structured data, graph algorithms, and machine learning, all in a single framework. This makes it a one-stop-shop for all your BigData crunching needs.
Features of Spark
Fast: Data processing up to 100x faster than MapReduce, both in-memory and on disk
Powerful: Write sophisticated parallel applications quickly in Java, Scala, or Python without having to think in terms of only “map” and “reduce” operators
Integrated: Spark is deeply integrated with CDH, able to read any data in HDFS and deployed through Cloudera Manager
Advantages of Spark
In practice, it is said that Spark is 10x faster than Hadoop on average.
Agility compared to the monolithic aspect of Hadoop: Spark allows rapid changes, thanks to loading the data into memory and interacting with it in a rapid manner. The shell (REPL) is great to test things out.
Data scientists & non-data engineers can use Spark through Python.
Newer platform with multiple tools like Machine learning, Graph and streaming included, with strong community support.
Scala is superior for data processing thanks to its higher level of abstraction. Although Spark supports Java, it is recommended to use Scala in Spark as a non-functional programming will make coding less intuitive and lower level. Also using Scala will make debugging will be easier. A combination of using an IDE (for API auto completion and data typing) and REPL (interactive shell) s actually best for efficiency.
Spark’s core concept is an in-memory execution model which enables caching of job data in memory, instead of fetching it from disk every time, like MapReduce does. This can speed up the execution of jobs up to 100 times, compared to the same jobs in Hadoop. This has the biggest effect on iterative algorithms, like machine learning, graph algorithms and other types of workloads that need to reuse data and it is a huge performance improvement over classic MapReduce jobs.
Spark Core is the basic component on which the other four components depend. Also pictured are various storage systems where Spark can access data from: distributed storage systems like HDFS, GlusterFS, S3 and similar; distributed databases like Cassandra, Impala, Hive, HBase, Hypertable, and others; but also classic relational databases, such as Oracle, PostgreSQL or DB2.
Spark Core contains basic Spark functionalities required for running jobs and needed by other components. The most important of these is the RDD concept, or resilient distributed dataset, which is the main element of Spark API. It is an abstraction of a distributed collection of items with operations and transformations applicable to the dataset. It is resilient because it is capable of rebuilding datasets in case of node failures. Spark Core also provides means of information sharing between computing nodes with broadcast variables and accumulators. Other fundamental functions, like networking, security, scheduling and data shuffling, are also part of the Spark Core.
Spark SQL is the newest Spark component, but very actively developed. It provides functions for manipulating large sets of distributed, structured data using SQL (actually, an SQL subset supported by Spark) and Hive SQL language (HQL). Spark SQL can also be used for querying JSON data as well as for writing and reading Parquet files, which is an increasingly popular file format that allows for storing schema along with the data. It provides a query optimization framework called Catalyst that can be extended by custom optimization rules and includes a Thrift server, which can be used by external systems, such as BI tools, to query data through Spark SQL using classic JDBC and ODBC protocols.
Spark Streaming is a framework for ingestion of real-time streaming data from various sources. The supported sources include HDFS, Kafka, Flume, Twitter, ZeroMQ and custom ones. Its operations recover from failure automatically which is, of course, very important for online data processing. Spark Streaming can be combined with other Spark components in a single program unifying real-time processing with machine learning, SQL and graph operations, which is something not seen in the Hadoop ecosystem.
Graphs are data structures comprised of vertices and edges connecting them. GraphX provides functions for building graphs and implementations of the most important algorithms of the graph theory, like page rank, connected components, shortest paths, SVD++ and others. It also provides Pregel message-passing API, the same API for large scale graph processing implemented by Apache Giraph, a project with implementations of graph algorithms and running on Hadoop.
Spark MLlib is a library of machine learning algorithms grown from MLbase project at UC Berkeley. Supported algorithms include logistic regression, naive Bayes classification, SVM, decision trees, random forests, linear regression, k-means clustering and others.
