According to https://flume.apache.org/

Flume is a distributed, reliable, and available service for efficiently collecting, aggregating, and moving large amounts of log data. It has a simple and flexible architecture based on streaming data flows. It is robust and fault tolerant with tunable reliability mechanisms and many failover and recovery mechanisms. It uses a simple extensible data model that allows for online analytic application.

In this post we will describe how to install Flume and try simple experiments.


Flume is based on java. Please check if java is installed on your system before start installation.

Latest release is available at download page https://flume.apache.org/download.html


Download package apache-flume-1.7.0-bin.tar.gz, uncompress and put it in a folder.

Edit log4.properties to enable more log


Sample Application

Open a text editor

# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444

# Describe the sink
a1.sinks.k1.type = logger

# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

Save config file on a path like C:\flume\apache-flume-1.7.0-bin\conf\netcatBasicExample.conf


Make sure JAVA_HOME is set running

echo %JAVA_HOME%

if is empty you can set it

set JAVA_HOME=C:\Program Files\Java\jre1.8.0_66
