If someone is looking for a career option in data analytics field then they must know about the big data job market. There are various job openings in the market that require big data Hadoop skill. It is well known fact that the core of big data field is Hadoop. Learning Hadoop first is the best way to understand how the data analytics field works. Many of the professionals thinks that Hadoop is a software, well in actual it is a combination of frameworks not a single software.
Hadoop is an open source technology, Combination of various frameworks. They are all parts of Hadoop and each of them have their own role and responsibility. It’s important to have complete understanding of these components. Madrid Software Trainings in association with industry experts provides complete practical Hadoop training in Delhi which makes this institute as the best Hadoop institute in Delhiamong professionals. Let’s discuss the various components of big data Hadoop.
Hadoop Distributed File System (HDFS)
HDFS is probably the most important component of the Hadoop family. The concept was first started by Google way back in the year 2000 by the name of Google File System (GFS). Later yahoo works on that concept and develop Hadoop distributed file system. HDFS consists of two nodes – Name node and Data node. The name node manages and maintain the data nodes while data nodes are where the data actually is.
MapReduce
Data is processed in Hadoop with the help of MapReduce. It consists of two parts Map and Reduce. Map is used for sorting, grouping and filtering, while reduce summarizes the results.
Hbase – The database of Hadoop
Hbase is a non-relational database which is design to run on the top of HDFS. Which allows the data to store in a fault tolerant way.

Pig
This is also an important part of Hadoop. It has two parts Pig Latin and Pig run time. Pig Latin can be used to write application.
Hive
Hive is also one of the most popular framework developed by Facebook. Later it can be added to Hadoop ecosystem. It can process large data sets as well as real time data. Hive is highly scalable.

ReplyDeleteThe Hadoop ecosystem consists of several core components that work together to store, process, and analyze massive volumes of data efficiently. The four fundamental components are Hadoop Distributed File System (HDFS) for distributed data storage, YARN (Yet Another Resource Negotiator) for cluster resource management and job scheduling, MapReduce for distributed data processing, and Hadoop Common, which provides the shared libraries and utilities required by other Hadoop modules. These components form the foundation of Hadoop and are essential for understanding how large-scale data processing systems operate.

Mastering these technologies enables professionals to build scalable data pipelines, perform batch and real-time analytics, and manage enterprise-level Big Data applications, making them well prepared for careers in Data Engineering, Big Data Engineering, and Analytics.
