What is the best practices in debugging Mapr local instance mappers?

I'm more interested in debugging it using IDE than logs. Like using -Xdebug option. When trying to use
HADOOP_OPTS="$HADOOP_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5003" in a ./hadoop it doesn't stop on mapper.
