Hadoop Wiki: Why Choose Hadoop as a Profession?

Hadoop is Java-based distributed processing framework, which is used to process and store huge amount of structured or unstructured data and this data is stored on commodity hardware. Hadoop has given a big platform to the organizations, on which they can increase their processing power and handle boundless data. This open source software project is used in the organizations, which have huge amounts of data to analyze both structured and unstructured forms. The best example of the organizations, which use Hadoop is the banks, which need to analyze millions of transactions to draw patterns, while social networks may need to analyze billions of events and the ad-networks may need to analyze millions of clicks to draw any pattern.

This article discusses what Hadoop is, the components of Hadoop and whyone should learn Hadoop or the scope of Hadoop.

What is Hadoop?

As discussed above Hadoop is open source software, which is used to analyze a huge amount of data. Today vast amount of data is available due to social network and for the legacy system; it is quite difficult to analyze this data. Hadoop provides a core platform to structure the data so that it can be analyzed easily. Even before the advent of Big Data Hadoop the data storage was also expensive. Gartner and IBM defined Hadoop as:

Gartner defined Hadoop as “Big Data Hadoop is a Hadoop file system, some utilities, and MapReduce”. MervAdrian defined Hadoop as:

  1. H-Hadoop
  2. A-And
  3. D-Diverse
  4. O-Other
  5. O-Operating
  6. P-Platforms

According to IBM, Hadoop is defined as “Hadoop is a software project, which enables distributed processing of large data sets across clusters of commodity servers and has a very high degree of fault tolerance. The failures and defects can be detected at the application layer in Hadoop”

Various Processes of Hadoop

In Hadoop the single server can be scaled up to numerous servers and thousands of machines, these servers can offer local computation and storage and the basic concepts of Hadoop are listed below:

  • HDFS: HDFS is Hadoop Distributed File System which is used to increase the throughput and to provide more data access to the applications.
  • Map Reduce Technology: This YARN-based system can implement the parallel processing for the large datasets.
  • Hadoop YARN: YARN framework is of Hadoop, which is used to mainly for job scheduling and cluster resources.
  • Hadoop Common: Hadoop modules use Java libraries, these libraries are mainly used by Java files and Hadoop scripts.

Among above-listed concepts, MapReduce and HDFS are two basic and essential components of Hadoop. Hadoop is used in various sectors including financial, healthcare, education and many others. Across the globe, the companies have started to migrate the data to Hadoop to increase their efficiency and storage capacity.Following are a few most important characteristics of Hadoop:

These features make Hadoop a system, which is the most beneficial and can be used by any organization to handle unstructured data efficiently. The data can be structured using Hadoop tools and therefore can also be utilized for the analysis so that any decision can be made using the data.
