Hi -
I’m using IntelliJ and the WordCount example in Hadoop (which uses
MiniMRCluster). Is it possible to set an IntelliJ debugger breakpoint straight
into the map function of the mapper? - I’ve tried, but so far, the debugger
does not stop at the breakpoint.
Thanks!

You might also want to look into MRUnit[1]. It lets you mock the
behavior of the framework to test your map and reduce classes in
isolation. Can't discover all bugs, but a useful tool and works nicely
with IDE debuggers.
