Sqoop Flume Hdfs Sqoop is used to import data from a structured data source, such as an RDBMS Flume for moving bulk stream data to HDFs HDFs Distributed File system for storing data using the Hadoop ecosystem The Sqoop has a connector architecture. The connector knows how to connect to the appropriate data source

its inevitability.Since 2012, the word Big Data has been more and more mentioned, and now we have entered the era of big data. In this era of information explosion, the amount of data generated every day is very large. Big data is more than just about data, big Data has four features:large data volume, wide variety, low value density, fast aging high. Based on these characteristics, we need a thing that has the following features:1. Can store large amounts of data2. Can quickly process large am
