MapReduce is Hadoops native batch processing engine. Several components or layers (like yarn, hdfs, etc.) in modern versions of Hadoop allow easy processing of batch data. Since mapReduce is about permanent storage, it stores data on-disk, which means it can handle large datasets. MapReduce is scalable and has proved its efficacy to deal with tens of thousands of nodes. However, hadoops data processing is slow as MapReduce operates in various sequential steps. Real-Time Analysis, spark : It can process real-time data,.

Hadoop MapReduce is designed in a way to process a large volume of data on a cluster of commodity hardware. MapReduce can process data in batch mode. Data Processing, spark : Apache Spark is a good fit for both batch processing and stream processing, meaning its a hybrid processing framework. Spark speeds up batch processing via in-memory computation and processing optimization. Its a nice alternative for streaming workloads, interactive queries, and machine learning. Spark can also work with Hadoop and its modules. Its real-time data processing capability makes Spark a top choice for big data analytics. Its resilient distributed dataset (RDD) allows Spark to transparently store data in-memory and send to disk only whats important or needed. As bill a result, a lot of time that's spent on the disk read and write is saved. Hadoop : Apache hadoop provides batch processing. Hadoop develops a great deal in creating new algorithms and component stack to improve access to large scale batch processing.

In this article, we will cover the differences between Spark and Hadoop report MapReduce. Introduction, spark : It is an open-source big data framework. It provides a faster and more general-purpose data processing engine. Spark is basically designed for fast computation. It also covers a wide range of workloads — for example, batch, interactive, iterative, and streaming. Hadoop MapReduce : It is also an open-source framework for writing applications. It also processes structured and unstructured data that are stored in hdfs.
