Flume PDF

Flume is a distributed system for collecting, aggregating, and moving large amounts of log data from different sources to a centralized data store. It uses agents that contain sources to collect data, channels to buffer data, and sinks to export the data to destinations such as HDFS. Common sources include the Avro, exec, and file sources, channels include memory and file channels, and sinks include HDFS, logger, and file roll sinks. Flume is configured using text configuration files defining the agents and components.
