Hi Mason,
It looks like you are manually loading chukwaConf.addResource(new
Path(...)), this should not be necessary. Instead, you might want to
do something like:
export CLASSPATH=${CLASSPATH}:/home/rainerdun/project/chukwa-0.5.0/conf
in chukwa-env.sh
This should enable to load Hadoop configuration from classpath without
having to explicitly addResource in java code. addResource should
refer to a .xml file rather than a directory. Hope this helps.
regards,
Eric
