I'm using the 0.9.4 tar distro and running through the docs, when I got up to 
this point 
http://archive.cloudera.com/cdh/3/flume/UserGuide/index.html#_tiering_flume_nodes_agents_and_collectors

And tried to use this config (through the web console) 

10.0.1.150 : console | agentSink("localhost",35853) ;
collector : collectorSource(35853) | console ;

There was a big bang….

com.cloudera.flume.conf.FlumeSpecException: Parser error: unexpected 
'collector' at position 0 line 2: '10.0.1.150 : console | 
agentSink("localhost",35853) ;
collector : collectorSource(35853) | console ;'
        at com.cloudera.flume.conf.FlumeSpecGen.generate(FlumeSpecGen.java:278)

        at 
com.cloudera.flume.master.CommandManager$ExecThread.run(CommandManager.java:236)

My work around was to change the collector flume node name from "collector" to 
"coll" and this then worked as a config

10.0.1.150 : console | agentSink("localhost",35853) ;
coll : collectorSource(35853) | console ;

Is collector a  token in the Antlr grammar ? 

Cheers
