Hi Guys,

I installed flume in my system. But when I start flume service using the below command, I got an error.

flume-ng agent –n agent1 –f /home/hadoop/HADOOP/apache-flume-1.6.0-bin/conf/twitter.conf
ERROR node.Application: A fatal error occurred while running. Exception follows. org.apache.commons.cli.MissingOptionException: Missing required option: n

Hi@akhtar,

I think you missed to add the conf. directory in your command. You need to specify the agent name, the config directory, and the config file on the command line to start the flume service.

bin/flume-ng agent -n $agent_name -c ./conf/ -f conf/twitter.conf

Hope this will help.
