Apache Flume NG replaced the original master/collector architecture with lightweight agents that can be wired together to form flexible data flows. This guide explains what changed with Flume NG, how the agent–channel–sink model works, and walks through simple configurations for syslog ingestion to a console logger and to HDFS. It’s aimed at engineers who still operate Flume in legacy estates or need to understand it for migrations. From Flume to Flume NG Apache Flume is a distributed log and event collection service. With Flume NG, the project moved away from the original master/client and node/collector design and adopted a simpler, more robust architecture based on standalone agents. Key changes introduced by Flume NG: No external coordination service required for basic operation. No master/client or node/collector roles—only agents . Agents can be chained together to build arbitrary flows and fan-in/fan-out patterns. Lightweight runtime; small heap sizes are s...
