Hi, I would like to debug the shuffle phase from a Reducer, but I
can't because the Reducer starts as a new process. I've tried all the
options that some pages says, but it doesn't work in the way that I
want.
I've tried the IsolationRunner class and the LocaJobRunner, but I
couldn't put them to w
I've other idea that I don't know how to do it. Is it possible to set Xdebug
parameter to the ReduceTask that is instanced by a JVM of the MapRed? If
it's possible, I could connect the debugger to that thread, right?

Hi,
I really need to debug the threads the ReduceTask will launch, and not using
unit tests. The reason is that I'm seeing what's happening in the ReduceTask
to do some changes to the code for myself. So, I was trying to debug the
ReduceTask setting the following in mapred-site.xml
mapred.job.
If you want to step through a full map / reduce job, the easiest way
to do this is to run a job using the local job runner in your IDE. The
local job runner will run the MR job in a single thread making it very
easy to debug. You will want to use the local file system and a small
amount of data dur
