An overview of Hadoop – the foundation of Big Data management

Big Data has thrown up many challenges that resulted in rapid technological developments to enable efficient data handling and management. There is an ever-increasing demand for more and more data, and Gigabytes that seemed quite large not very long ago is now a thing of the past. We now measure data in Terabytes, and it is only a matter of time before it becomes insufficient and irrelevant. The fast pace of data growth is matched by the rapid progress of new inventions and discoveries in the technological field. This is reflected in the development of Hadoop, an open-source programming framework based on Java that is capable of handling efficiently massive data sets for storage and processing in an environment that uses several computing devices. The advent of Hadoop has changed the perception of handling unstructured data, which forms the bulk of Big Data.

A PC data set is characterized as any coordinated assortment of information and the specialized definition is that it's anything but an assortment of mappings, tables, questions, reports, sees, and different items according to Wikipedia. The entire thought of a data set is to have the option to demonstrate objects on the planet in a genuine manner that will uphold the simple handling of the hidden information. To deal with an information base, you need to utilize a data set administration framework, a specific piece of programming whose reason of being is to cooperate with the client, different applications, and the data set itself to secure and examine the information.

The Hadoop advantage

Find out from any DBA consultant how the newfound Hadoop has made their lives easy in managing unstructured data.  Firstly, it can handle thousands of terabytes of data and supports the running of applications on systems that has many commodity hardware nodes. Secondly, it has the capability of keeping the system running in the event of a node failure, which gives a big boost to data management, as there is a minimum possibility of data losses. Thirdly, it transfers data at high speeds by taking advantage of its distributed file system like Extratorrent 2. All big data processing tasks that have to handle extensive data now swear by Hadoop that has become the foundation of Big Data management.


The framework has two main features – The Hadoop Distributed File System (HDFS) handles file storage and MapReduce that processes stored data. The high data handling is possible due to the system’s ability to break large files into blocks of 128 MB files (64MB is the default size). Copies of these files are stored on several servers so that their retrieval is possible even if there is a hardware failure. DBA consultants know well that the HDFS is responsible for storing files, managing, and providing access to it. 


The feature MapReduce facilitates processing data blocks in parallel instead of doing it serially.  Segments of your applications run on the same server where you want to place the particular data block.  Suppose you have data for ten years fragmented into small files and spread over some servers. When you are processing the data, the system processes data residing on all servers at the same time instead of doing it one at a time. Since each block that is processed is not more than 128 MB, the processing takes petite time, and doing it together means that all tasks finish within that time only.


Remote DBA service providers are well versed in Hadoop and can provide round-the-clock service for database maintenance. If your business has a huge amount of data to handle that is growing very fast, but funds for managing it are a constraint then Hadoop is perhaps the most economical solution for you.
