I am a newbie dev. I would like to generate a call graph for Hadoop inorder

There's a trick Log4J where you can get the logger to push out the class
and method making a log call -add
%c.%M()
to your logg pattern, e.g
log4j.appender.stdout.layout.ConversionPattern=%d{DATE} %-5p [%t]
%c.%M() -- %m%n
Nobody uses this in production as it causes a stack trace to be created
for every logging op, but it's good for tracking down problems, or here,
getting an understanding of what goes where
