Execute the flume example
kashif khan 2012-11-28, 12:25
Hi,

I just started reading the flume document. I am trying to run the example
of flume. when trying to execute the command, I am getting the following
message on terminal and warning that  Please initialize the log4j system
properly. I am not getting any output as mentioned in flume document.

First time when I execute its work and I was getting what I have typed on
another terminal. Now I am executing not getting the output.
my agent conf file as:

agent1.sources = source1
agent1.sinks = sink1
agent1.channels = channel1

# Describe/configure source1
agent1.sources.source1.type = netcat
agent1.sources.source1.bind = localhost
agent1.sources.source1.port = 44444

# Describe sink1
agent1.sinks.sink1.type = logger

# Use a channel which buffers events in memory
agent1.channels.channel1.type = memory
agent1.channels.channel1.capacity = 1000
agent1.channels.channel1.transactionCapactiy = 100

# Bind the source and sink to the channel
agent1.sources.source1.channels = channel1
agent1.sinks.sink1.channel = channel1
Command as:
root@hadoop1:/usr/lib/flume-ng# bin/flume-ng agent -c /etc/flume-ng/conf -f
/etc/flume-ng/conf/flume.conf -n agent1 -Dflume.root.logger= INFO, console
Message on Terminal.
