- Highly scalable as it operates in a distributed environment
- Redundant design ensures fault tolerance
- Can be used in a cloud environment or commodity hardware
- Store data in any format
- Less efficient than other modern frameworks
- Requires significant expertise to set up, maintain, and upgrade
This tool has five main modules:
- Hadoop Distributed File System (HDFS) can store large data sets across nodes in a fault-tolerant manner.
- Yet Another Resource Negotiator (YARN) is responsible for planning tasks, managing cluster resources, and scheduling jobs running on Hadoop.
- MapReduce is the big data processing engine and programming model that enables the parallel computation of large data sets.
- Hadoop Common consists of libraries and utilities required by other Hadoop modules.
- Hadoop Ozone is an object store optimized for billions of small files.

Frequently Asked Questions
What’s the difference between data science, AI, and ML?
Data Science is a broad field of study that involves pre-processing, analysis, and visualization of structured and unstructured data. The insights gained from data are then applied to a wide range of application domains.
Artificial Intelligence means teaching a machine to mimic human behavior in some way. The goals of AI research include knowledge representation, planning, learning, reasoning, natural language processing, perception, and the ability to manipulate objects.
Machine learning is a subset of AI that focuses on how to use data and algorithms to imitate the way humans learn. The more data (also called training data) the ML model gets, the more accurately it makes predictions without being explicitly programmed to do so.
What are the steps involved in data science?
Data science involves six iterative steps.
- Plan: Define a project and its estimated results.
- Build a data model: Use an appropriate data science tool to create machine learning models.
- Evaluate: Use evaluation metrics and visualization to measure model performance against new data.
- Explain (in simple terms) the internal mechanics of machine learning models.
- Deploy the well-trained model in a secure and scalable environment.
- Monitor the model to ensure that it is working properly.
What to consider before selecting a data science tool?
Following are the key features you should consider in a data science platform:
- It should allow multiple users to work together on the same model
- Should include support for the latest open-source applications
- Must be scalable
- Should be able to automate tedious tasks
- Should have the capability to easily deploy models into production
How data science helps business?
Data science plays a major role in analyzing the health of businesses. It extracts valuable information from raw data and predicts the success rate of the company’s products and services. It also helps in identifying inefficiencies in manufacturing processes, targeting the right audience, and recruiting the right talent for the organization.
Some sectors use data science to increase the security of their business and protect sensitive information. Banks, for example, use machine learning algorithms to detect fraud based on customer’s usual financial activities. These algorithms have been proven far more effective and accurate in identifying frauds than manual investigations.
According to the GlobalNewswire report, the global data science platform market will reach $224 billion by 2026, growing at a CAGR of 31 percent.
