>Your JAVA_HOME is pointing to a java 1.4 JDK; needs to be 1.6.

Thank you!!! :)
Indeed - JAVA_HOME was not set so it probably used some old Java engine I had 
lying around. 

I would appreciate some additional help in setting this up, I hope I'm not 
bothering you too much. 

I am following this guide:

Right now I am trying to run `bash bin/` but I get this 

I guess my classpath is incomplete, but I can't figure out what is missing (in 
which jar CollectorStub is). From
$ java ... -classpath ${CHUKWA_CONF_DIR}:${HADOOP_CONF_DIR}:${CLASSPATH}:

Also, there are some things that are not clear to me in conf/chukwa-collector-

1) writer.hdfs.filesystem - I want to output to HDFS. Does that mean I have to 
specify hdfs://... style path? In Quick Start is says "path to the namenode", 
but that is probably not enough?

2) chukwaCollector.outputDir - is this the subdir of previous setting or is 
this the local output directory that Collector writes to ebfore it commits to 

3) chukwaCollector.rotateInterval - the default value is 5 minutes, is there 
any reason for it to be specified in milliseconds? Is this the time between 
commits to HDFS?

Thank you again for your help, I appreciate it.

Kind regards,
