Basics of Hadoop Cluster

  • Last Updated : 22 Jun, 2020

Hadoop Cluster is stated as a combined group of unconventional units. These units are in a connected with a dedicated server which is used for working as a sole data organizing source. It works as centralized unit throughout the working process. In simple terms, it is stated as  a common type of cluster which is present for the computational task. This cluster is helpful in distributing the workload for analyzing data. Workload over Hadoop cluster is distributed among several other nodes, which are working together to process data. It can be explained by considering the following terms:

  1. Distributed Data Processing: In distributed data processing, the map gets reduced and scrutinized from a large amount of data. It get assigned a job tracker for all the functionalities. Apart from the job tracker, there is a data node and task tracker. All these play a huge role in processing the data.
  2. Distributed Data Storage: It allows  storing a huge amount of data in terms of name node and secondary name node. In this both the nodes have a data node and task tracker.

How does Hadoop Cluster Makes Working so Easy?

It plays important role to collect and analyze the data in a proper way. It is useful in performing a number of tasks which brings out the ease in any task. 

  • Add nodes: It is easy to add nodes in the cluster to help in other functional areas. Without the nodes, it is not possible  to scrutinize the data from unstructured units.
  • Data Analysis: This special type of cluster which is compatible with parallel computation to analyze the data.
  • Fault tolerance: The data stored in any node remain unreliable. So, it creates a copy of the data which is present on other nodes.

Uses of Hadoop Cluster:

  1. It is extremely helpful in storing different type of data sets.
  2. Compatible with the storage of the huge amount of diverse data.
  3. Hadoop cluster  fits best under the situation of parallel computation for processing the data.
  4. It is also helpful for data cleaning processes.

Major Tasks of Hadoop Cluster:

  1. It is suitable for performing data processing activities.
  2. It is a great tool for collecting bulk amount of data.
  3. It also adds great value in the data serialization process.

Working with Hadoop Cluster:

While working with Hadoop Cluster it is important to understand its architecture as follows :

  • Master Nodes: Master node plays a great role in collecting a huge amount of data in the Hadoop Distributed File System (HDFS). Apart from that, it works to store data with parallel computation by  applying Map Reduce.
  • Slave nodes: It is responsible for the collection of data. While performing any computation, the slave node is held responsible for any situation or result.
  • Client nodes: The Hadoop is installed along with the configuration settings.Hadoop Cluster demands to load the data, it is the client node who is held responsible for this task.


  1. Cost-effective: It offers  cost-effective solution for data storage and analysis.
  2. Quick process: The storage system in Hadoop cluster runs in a fast way to provide speedy results. In the case of the huge amount of data is available, it is a helpful tool.
  3. Easy accessibility: It helps to access the new sources of data easily. Moreover used to collect both the structured as well as unstructured data.


This type of software is having a wide scope area as it  is extremely usable and beneficial software for a number of large, small, or medium-sized enterprises. Following are  certain reasons which make it high on demand, which is mentioned below:

  • Innovative: It is an innovative software which decreased the demand for other traditional sources .
  • Universal applicability: It is a vast concept which is available in organization, irrespective of the size.
