Use Flume and Sqoop to import data to HDFS, HBase and Hive from a variety of sources, including Twitter and MySQL

Let’s parse that.

Import data : Flume and Sqoop play a special role in the Hadoop ecosystem. They transport data from sources like local file systems, HTTP, MySQL and Twitter which hold/produce data to data stores like HDFS, HBase and Hive. Both tools come with built-in functionality and abstract away users from the complexity of transporting data between these systems. 

Flume: Flume Agents can transport data produced by a streaming application to data stores like HDFS and HBase. 

Sqoop: Use Sqoop to bulk import data from traditional RDBMS to Hadoop storage architectures like HDFS or Hive.
