export FLUME_CONF_DIR=$FLUME_HOME/conf
export FLUME_CLASSPATH=$FLUME_HOME_DIR
export PATH=$FLUME_HOME/bin:$PATH and I am doing this under root user, below is the error message: 16/06/28 10:48:21 ERROR node.PollingPropertiesFileConfigurationProvider: Failed to load configuration data. Exception follows.
