Hello.
I am not sure anyone can see this comment, but I am writing here.
I tried to patch the latest file to use zookeeper.
Since that patch is little bit outdated, I manually did it with flume-ng-1.5.0.
And I compiled it and run with command below:
bin/flume-ng agent --conf ./conf/ -f conf/flume.conf
-Dflume.root.logger=DEBUG,console -n agent1 -z localhost:2181
And getting the error below:
2014-07-28 17:09:07,953 (lifecycleSupervisor-1-0) [ERROR -
org.apache.flume.lifecycle.LifecycleSupervisor$MonitorRunnable.run(LifecycleSupervisor.java:305)]

If anyone has any idea, kindly let me know.
Thanks in advance.
