Hadoop is an open-source software with a framework that is used to process! It helps with large amounts of data and big data and compiles with distributed computing environments! Hadoop is an open source that provides framework data and performs computations. It is framework-based Java programming itself! This open source is used for storing and processing large amounts of data! MapReduce programming model allows for the parallel processing of large datasets. So, in this article, we will talk about what Hadoop is. So stay tuned!
Hadoop is an open-source framework after Apache and is used to store, process, and analyze data, which is enormous in volume. Hadoop is on Java paper and not OLAP (online analytical processing). It is used for batch/offline processing. Facebook, Yahoo, Google, Twitter, LinkedIn, and countless more are using it. Moreover, it can be scaled up just by calculating nodes in the cluster.
The Hadoop Distributed File System (HDFS) is a dispersed file system for Hadoop. It contains a master/enslaved person construction. This architecture consists of a single NameNode that plays the role of master, and multiple DataNodes perform the role of an enslaved person.
Both NameNode and DataNode are capable enough to run on commodity machinery. Java is used to develop HDFS. So, any machine that supports Java language can run the NameNode and DataNode software.
MapReduce exists when the client's application submits the MapReduce job to Job Tracker. In answer, the Job Tracker sends the request to the appropriate Task Trackers. From time to time, the TaskTracker fails or time out. In such a case, that part of the job is rescheduled.
Doug Cutting started the Hadoop in addition to Mike Cafarella in 2002. Its origin was the Google File System paper published by Google.
Let's focus on the history of Hadoop in the following steps: -

Hadoop uses distributed storage and parallel processing to handle big data, in addition to analytics jobs, breaking workloads down into smaller jobs that can be run simultaneously.
Technically, Hadoop is not a database such as SQL or RDBMS. Instead, the Hadoop framework gives employers a processing solution for various database types. Hadoop is a software ecosystem that allows businesses to handle vast sums of data in short amounts of time.
Using Hadoop, you can analyze sales data contrary to many factors. For instance, if you analyzed sales data against meteorological conditions data, you could determine which products sell best on hot days, cold days, or rainy days. Or, what if you analyzed sales data by time besides day?
The Nutch project was divided into the web crawler portion, which endured as Nutch, and the distributed computing and processing portion, which was converted to Hadoop (named after Cutting's son's toy elephant).
Apache Hadoop is an open-source framework used to competently store and process large datasets ranging in size from gibibytes to petabytes. Instead of using one large computer to store and course the data, Hadoop allows clustering multiple computers to analyze massive datasets in parallel more quickly.
