What is the architecture of Hadoop?
The Hadoop architecture is a package of the file system, MapReduce engine and the HDFS (Hadoop Distributed File System). The MapReduce engine can be MapReduce/MR1 or YARN/MR2. A Hadoop cluster consists of a single master and multiple slave nodes.
What is Hadoop HDFS architecture with diagram?
Apache Hadoop HDFS Architecture follows a Master/Slave Architecture, where a cluster comprises of a single NameNode (Master node) and all the other nodes are DataNodes (Slave nodes). HDFS can be deployed on a broad spectrum of machines that support Java.
What are some of the major components of Apache Hadoop?
There are three components of Hadoop.
- Hadoop HDFS – Hadoop Distributed File System (HDFS) is the storage unit of Hadoop.
- Hadoop MapReduce – Hadoop MapReduce is the processing unit of Hadoop.
- Hadoop YARN – Hadoop YARN is a resource management unit of Hadoop.
What is Apache Hadoop used for?
Apache Hadoop software is an open source framework that allows for the distributed storage and processing of large datasets across clusters of computers using simple programming models.
What are the supplementary tools of Apache MapReduce?
Top 20 essential Hadoop tools for crunching Big Data
- Hadoop Distributed File System. The Hadoop Distributed File System (HDFS) is designed to store very large data sets reliably, and to stream those data sets at high bandwidth to user applications.
- Hbase.
- HIVE.
- Sqoop.
- Pig.
- ZooKeeper.
- NOSQL.
- Mahout.
What is Apache Hadoop and explain its types?
Apache Hadoop software is an open source framework that allows for the distributed storage and processing of large datasets across clusters of computers using simple programming models. In this way, Hadoop can efficiently store and process large datasets ranging in size from gigabytes to petabytes of data.
What is Apache Hadoop Geeksforgeeks?
Apache Hadoop: It is an open-source software framework that built on the cluster of machines. It is used for distributed storage and distributed processing for very large data sets i.e. Big Data. It can mine any form of data i.e. structured, unstructured, or semi-structured.
Which architecture is used by HDFS and explain one example?
HDFS is based on a leader/follower architecture. Each cluster is typically composed of a single NameNode, an optional SecondaryNameNode (for data recovery in the event of failure), and an arbitrary number of DataNodes.
What is Apache HDFS?
HDFS is a distributed file system that handles large data sets running on commodity hardware. It is used to scale a single Apache Hadoop cluster to hundreds (and even thousands) of nodes. HDFS is one of the major components of Apache Hadoop, the others being MapReduce and YARN.
What is the core concept behind Apache Hadoop framework?
The core of Apache Hadoop consists of a storage part, known as Hadoop Distributed File System (HDFS), and a processing part which is a MapReduce programming model. Hadoop splits files into large blocks and distributes them across nodes in a cluster.

What is Hadoop architecture and how it works?
Let us now start with Hadoop Architecture. The goal of designing Hadoop is to develop an inexpensive, reliable, and scalable framework that stores and analyzes the rising big data. Apache Hadoop is a software framework designed by Apache Software Foundation for storing and processing large datasets of varying sizes and formats.
What is the difference between Hadoop MapReduce and HDFS?
HDFS is a set of protocols used to store large data sets, while MapReduce efficiently processes the incoming data. A Hadoop cluster consists of one, or several, Master Nodes and many more so-called Slave Nodes.
What is the Hadoop distributed file system?
The Hadoop Distributed File System (HDFS), YARN, and MapReduce are at the heart of that ecosystem. HDFS is a set of protocols used to store large data sets, while MapReduce efficiently processes the incoming data. A Hadoop cluster consists of one, or several, Master Nodes and many more so-called Slave Nodes.
What’s new in yarn for Hadoop?
As the de-facto resource management tool for Hadoop, YARN is now able to allocate resources to different frameworks written for Hadoop. These include projects such as Apache Pig, Hive, Giraph, Zookeeper, as well as MapReduce itself.
