Which is the design architecture of HDFS?

HDFS has a Master-slave architecture. The daemon called NameNode runs on the master server. It is responsible for Namespace management and regulates file access by the client.

What is HDFS architecture and its concepts?

HDFS architecture. The Hadoop Distributed File System (HDFS) is the underlying file system of a Hadoop cluster. It provides scalable, fault-tolerant, rack-aware data storage designed to be deployed on commodity hardware. Several attributes set HDFS apart from other distributed file systems.

What is Hadoop HDFS architecture with diagram?

HDFS holds very large amount of data and provides easier access. To store such huge data, the files are stored across multiple machines. These files are stored in redundant fashion to rescue the system from possible data losses in case of failure. HDFS also makes applications available to parallel processing.

What is HDFS architecture in big data?

Apache HDFS or Hadoop Distributed File System is a block-structured file system where each file is divided into blocks of a pre-determined size. These blocks are stored across a cluster of one or several machines.

What are the different architectures in 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 in detail ques10?

The Hadoop Distributed File System (HDFS) is designed to provide a fault-tolerant file system designed to run on commodity hardware. The primary objective of HDFS is to store data reliably even in the presence of failures including Name Node failures, Data Node failures and network partitions.

What is HDFS and its components with diagram?

HDFS comprises of 3 important components-NameNode, DataNode and Secondary NameNode. HDFS operates on a Master-Slave architecture model where the NameNode acts as the master node for keeping a track of the storage cluster and the DataNode acts as a slave node summing up to the various systems within a Hadoop cluster.

What is the purpose of 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 high level architecture of Hadoop?

HDFS: The Hadoop Distributed File System provides unrestricted, high-speed access to the application data. Hadoop YARN: This technology accomplishes the scheduling of jobs and efficient management of the cluster resource. MapReduce: A highly efficient methodology for parallel processing of huge volumes of data.
