Hadoop MapReduce uses disk-based processing.ĭue to these weaknesses of Hadoop MapReduce Apache Spark come into the picture.

Java being heavily exploited by cybercriminals this may result in numerous security breaches.

Since the maximum framework is written in Java there is some security concern.

Use only Java for application building.

Some of the drawbacks of Hadoop MapReduce are: Apache Spark was developed to overcome the limitations of Hadoop MapReduce cluster computing paradigm. This section of Spark notes, we cover the needs of Spark.

Spark became a project of Apache Software Foundation in the year 2013 and is now the biggest project of Apache foundation. Spark has open sourced in the year 2010 under BSD license. The first users of Spark were the group inside UC Berkeley including machine learning researchers, which used Spark to monitor and predict traffic congestion in the San Francisco Bay Area. Spark Notes – Spark HistoryĪpache Spark is a subproject of Hadoop developed in the year 2009 by Matei Zaharia in UC Berkeley’s AMPLab. To keep this in mind we have also provided Spark video tutorial for more understanding of Apache Spark. The in-memory computing means using a type of middleware software that allows one to store data in RAM, across a cluster of computers, and process it in parallel.Īs we know that the images are the worth of a thousand words. That increases the processing speed of an application. The key feature of Spark is that it has in-memory cluster computation capability. Spark is independent of Hadoop because it has its own cluster management system. There is a common belief that Apache Spark is an extension of Hadoop, which is not true. Spark is highly accessible and offers simple APIs in Python, Java, Scala, and R. MapReduce is a programming paradigm that allows scalability across thousands of server in Hadoop cluster. Spark extends Hadoop MapReduce to next level which includes iterative queries and stream processing. For example, Spark can access any Hadoop data source and can run on Hadoop clusters. Spark is designed in such a way that it integrates with all the Big data tools. It is a general purpose, cluster computing platform. It is designed in such a way that it can perform batch processing (processing of the previously collected job in a single batch) and stream processing (deal with streaming data). Spark Notes – What is Spark?Īpache Spark is an open source, wide range data processing engine with revealing development API’s, that qualify data workers to accomplish streaming in spark, machine learning or SQL workloads which demand repeated access to data sets.
