echo "Running on hadoop, using $HADOOP_BINARY and HADOOP_CONF_DIR=$HADOOP_CONF_DIR"

if [ "$MAHOUT_JOB" = "" ] ; then
echo "ERROR: Could not find mahout-examples-*.job in $MAHOUT_HOME or $MAHOUT_HOME/examples/target, please run 'mvn install' to create the .job file"
exit 1
else
case "$1" in
(hadoop)
shift
export HADOOP_CLASSPATH=$MAHOUT_CONF_DIR:${HADOOP_CLASSPATH}:$CLASSPATH
exec "$HADOOP_BINARY" "$@"
;;
(classpath)
echo $CLASSPATH
;;

echo "MAHOUT-JOB: $MAHOUT_JOB"
export HADOOP_CLASSPATH=$MAHOUT_CONF_DIR:${HADOOP_CLASSPATH}
