             Summary: Ability to override any parameter from the configuration file
                 Key: FLUME-2351
                 URL: https://issues.apache.org/jira/browse/FLUME-2351
             Project: Flume
          Issue Type: Improvement
          Components: Node
    Affects Versions: v1.5.0
            Reporter: Krisztian Horvath


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
