Great tools for a Big Data.
The data researchers no longer depend only on interviews, surveys, observational studies to collect data. Instead, they have switched to the faster ways of data collection which includes leveraging internet, cameras, smartphones, drones, bots and many more. Later, the collected data is used by organization / governments to make business decisions. But, before that, they require a device or system which can store and secure such big data sets. One such system is Hadoop File Distribution System, commonly known as HDFS. If you are new to HDFS architecture, let me provide a simple picture of what it does: In simple terms, HDFS stores raw data is such a manner that the data is easily extracted at a later stage.
