I have chukwa 0.4.0 and hadoop 0.20.2 installed on a small cluster.
When I run bin/start-agents.sh I get the following:

A similar error reported last year seemed to be related to the Hadoop
path. This is what I have changed from the chukwa-env.sh defaults:
export HADOOP_HOME="/home/ngc/hadoop-0.20.2"
export HADOOP_CONF_DIR="/home/ngc/hadoop-0.20.2/conf"
export HADOOP_JAR=${HADOOP_HOME}/hadoop-*-core.jar
export JAVA_PLATFORM=Linux-amd64-64
Any idea as to what I am doing wrong?
