Description

To start flume agents dynamically it comes handy to be able to override parameters of a base configuration file without actually touching and modifying it, for example change the bind port.

Example:

agent.sources.avro-collection-source.bind = localhost
agent.sources.avro-collection-source.port = 50000
agent.sinks.hdfs-sink.hdfs.path = hdfs://localhost:9000/flume
agent.channels.memoryChannel.capacity = 20000

flume-ng agent -n agent -f flume.conf
-o avro-collection-source.bind=0.0.0.0
-o avro-collection-source.port=30000
-o hdfs-sink.hdfs.path=hdfs://localhost:9000/data
-o memoryChannel.capacity=30000
