What is Hadoop ecosystem and components?

Introduction: Hadoop Ecosystem is a platform or a suite which provides various services to solve the big data problems. It includes Apache projects and various commercial tools and solutions. There are four major elements of Hadoop i.e. HDFS, MapReduce, YARN, and Hadoop Common. … HDFS: Hadoop Distributed File System.

Which of the Hadoop tools is responsible for data management?

YARN is called as the operating system of Hadoop as it is responsible for managing and monitoring workloads. It allows multiple data processing engines such as real-time streaming and batch processing to handle data stored on a single platform.

How many different technologies are in the Hadoop ecosystem?

And, although the name has become synonymous with big data technology, in fact, Hadoop now represents a vast system of more than 100 interrelated open source projects. In the wide world of Hadoop today, there are seven technology areas that have garnered a high level of interest.

Which component of Hadoop ecosystem is used for migrating data from Rdbms?

Tools to migrate data from RDBMS to Hadoop HDFS

Sqoop acts as the intermediate layer between the RDBMS and Hadoop to transfer data. It is used to import data from the relational database such as MySQL / Oracle to Hadoop Distributed File System (HDFS) and export data from the Hadoop file system to relational databases.

What are the main components of MapReduce?

Generally, MapReduce consists of two (sometimes three) phases: i.e. Mapping, Combining (optional) and Reducing.

  • Mapping phase: Filters and prepares the input for the next phase that may be Combining or Reducing.
  • Reduction phase: Takes care of the aggregation and compilation of the final result.
