Hire Hadoop Consultants For Any Job

Want To Hire a Freelance Hadoop Consultant

Hadoop comprises 4 modules:

• HDFS (Hadoop Distributed File System) –HSFS proposes improved data all through the conventional file systems besides higher fault tolerance as well as native support of big datasets.
• MapReduce – MapReduce is a framework that assists a program in doing parallel data computation. The map job takes input data before converting it into datasets that can get computed in some key value pairs.
• YARN (Yet Another Resource Negotiator) – YARN manages as well as screens resource usage and cluster nodes, and it schedules tasks and jobs.
• Hadoop Common – It proposes common libraries of Java that can be utilized all across modules.

Benefits of Hadoop

There are several benefits of Hadoop:

• Quick – In HDFS or Hadoop Distributed File System, the data that is distributed over the cluster assists in quicker retrieval. Again, the tools for processing the data are habitually on similar servers. So, it lessens the processing time.
• Cost-effective – Hadoop is open-source and it utilizes commodity hardware for storing data. Hence, it is a cost-effective solution in comparison to customary RDMS or relational database management systems.
• Scalable – The cluster of Hadoop can be stretched by including nodes in a cluster.
• Resilient to failure – Hadoop Distributed File System has got the property and with it, it can duplicate data over the network. Hence, if a node becomes down, Hadoop takes the next copy of data for using it. Commonly, data are copied thrice though the replication factor remains configurable.

The relation of Hadoop with big data

Hadoop does run on commodity servers and it can scale up for supporting many hardware nodes. The HDFS intends to propose fast access all across the nodes, and these features help Hadoop to turn into a foundational data mgmt. platform for bigger data analytics uses when it arose in the 2000s.

As Hadoop can store and process a huge assortment of data, it allows an organization to set up some data lakes. In the Hadoop data lake, some raw data is habitually stored. Hence, other analysts and data scientists can access full data sets. After this, the data gets filtered as well as prepared by IT or analytics teams for supporting various applications. 

A data lake commonly serves various purposes compared to a customary data warehouse that holds a cleansed set of transaction data. However, in a few instances, a company views its Hadoop data lakes in the form of modern-day data warehouses. Regardless of the method, the escalating role of huge data analytics in the decision-making of a business has turned effective data security and data governance processes into a top priority in Hadoop systems.
