Skills you'll gain: MapReduce
What is MapReduce? MapReduce is a part of the Apache Hadoop system, a framework that helps with processing vast amounts of data. In addition to MapReduce, Apache Hadoop includes other important components like the Hadoop Distributed File System (HDFS), Yarn, and Apache Pig.
MapReduce plays a key role in handling large datasets within the Hadoop ecosystem. It uses distributed and parallel algorithms to process data efficiently. This programming approach is commonly used in social media and e-commerce to analyze massive data collected from online users.
MapReduce is a part of the Hadoop framework, which is used for creating applications that can handle large amounts of data on extensive clusters of computers. It’s like a programming model that allows us to process extensive datasets across multiple computer clusters.
This approach enables data to be stored in a distributed manner, simplifying the management of massive volumes of data and large-scale computing.
MapReduce involves two primary tasks: ‘map’ and ‘reduce.’ The mapping task is done before the reducing task. During the mapping job, we divide the input dataset into smaller pieces, and these pieces are processed in parallel. The output from the mapping stage serves as input for the reducing stage. The reducers take the intermediate data from the mapping phase and transform it into smaller sets, ultimately producing the final output of the framework.
The MapReduce framework also helps in scheduling and monitoring tasks. If any task fails, the framework automatically retries it.
Even programmers with limited experience in distributed processing can use MapReduce easily. It can be implemented using various programming languages such as Java, Hive, Pig, Scala, and Python.
=> Comprehensive MapReduce is a self-paced course designed by Edureka. It is designed and created by Hadoop Experts, to provide you the skills and knowledge in the field of MapReduce Framework. This course will help you to solve the problems and use cases by efficiently utilising MapReduce skills and concepts.
Every class consists of practical tasks and assignments, which should be complete before the next class starts. This helps you in applying the theoretical and practical concepts, you learned during the course.
