debugging a mapreduce job

[kardes]

hi, I'd like to get into the map and reduce functions of the simple wordcount example using rmr2, using the debug() function in R.
I load rmr2:
library(rmr2)

and then try ( as suggested at https://github.com/RevolutionAnalytics/rmr2/blob/master/docs/tutorial.md)

rmr.options(backend = "local")
NULL

is what I get. What is exactly the procedure to achieve what I'd like to do. I simply would like get inside the map and reduce functions to see how things work together. Thanks.

After changing backend, as you did, use function debug as usual. It's
helpful to use named functions as map and reduce function, so that you can
enter debug(my.map.function). If you use anonymous functions, it's more
complicated.
