You have to manually start each node with its specific configuration.  However, you can put the configuration for all your different setups into one config file, but you will still need to place a copy of it on every machine.  Simply define which agent config to use with the --name param when starting.

Thanks,

Thank you both very much, I've been reading the documentation you sent me and this brings another question, is there a way to submit my flume configuration to a cluster or I have to manually start up each node with the its specific configuration?

Thank you!

+1 on what Roy said, with a minor terminology quibble: in Flume NG the Avro collector component is called the Avro Source.

Also, here are links to the docs with working image links and table of contents:

You would run a flume-ng instance on each node with an avro-sink.  Then on your collector machine you will run another flume-ng instance with an avro-collector.

If you run more than one collector you can setup sink groups and define that it does failover or load balancing.

The concept of a flume master from flume 0.9.x does not exist on flume-ng.  I personally use the node and collector configs in the same config file under a different agent name, and then keep them synced on all machines.

These two docs are pretty helpful:

Subject: Flume-ng - Distributed

Hi,

I'm new to Flume-ng, I'd like to ask you if you can tell me how I can accomplish to have an agent distributed in a cluster. I've have developed my own source and sink version that reads from a queue and the sink stores the messages read to hdfs. If I want to have this running in multiple instances, do I have to submit it on each node?

This is my conf file:
agent1.channels.channel1.type = memory
agent1.channels.channel1.capacity = 1000
agent1.channels.channel1.transactionCapacity = 1000

agent1.sources.source1.channels = channel1
agent1.sources.source1.type = MySource

agent1.sinks.sink1.channel = channel1
agent1.sinks.sink1.type = MySink

agent1.channels = channel1
agent1.sources = source1
agent1.sinks = sink1
I see that there is the concept of 'master' a 'node' in the previous version of flume, do I have something similar here?

Thanks,
Juan
