MapReduce is a programming model and processing technique designed for distributed computing and handling large data sets. It operates by dividing the data processing into two primary phases: the "Map" phase, which involves breaking down a complex task into smaller sub-tasks and processing them in parallel, and the "Reduce" phase, which...

HBase, short for Hadoop Database, is an open-source, distributed NoSQL database system designed for handling vast volumes of data. It operates within a distributed architecture, leveraging the Hadoop Distributed File System (HDFS) to store and manage data across multiple nodes in a cluster. Unlike traditional relational databases, HBase stores...

In our cassandra interview questions, we cover a broad spectrum of topics related to this distributed NoSQL database, assessing candidates' comprehension of Cassandra architecture, data modeling, and operational elements. Candidates might encounter questions delving into concepts such as eventual consistency, the CAP theorem, and the significance...

These Apache Sqoop Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of Apache Sqoop . As per my experience good interviewers hardly plan to ask any particular question during your interview, normally questions start with some basic concept...

Apache Hive interview questions span various facets of the platform, exploring topics essential for candidates to demonstrate their expertise in leveraging Hive for big data processing within the Hadoop ecosystem.

Apache Spark is an open-source cluster computing framework. Its primary purpose is to handle the real-time generated data.Spark was built on the top of the Hadoop MapReduce. It was optimized to run in memory whereas alternative approaches like Hadoop's MapReduce writes data to and from computer hard drives. So, Spark process the data much quicker...

Apache Oozie is the tool in which all sort of programs can be pipelined in a desired order to work in Hadoop’s distributed environment. Oozie also provides a mechanism to run the job at a given schedule. This tutorial explains the scheduler system to run and manage Hadoop jobs called Apache Oozie. It is tightly integrated with Hadoop stack...

Introduction to Big Data Big Data is a collection of large data sets that cannot be processed using standard computing techniques. It is not a simple technique or method but involves a lot of business and technology fields. The term ‘big data’ is self-explanatory − a collection of huge data sets that normal computing techniques cannot...
