Hadoop is working fine in Linux. In Windows (using cygwin) I can't get
mapred to work, though hdfs is ok. This is the stacktrace:
java.io.FileNotFoundException: File
E:/tmp/hadoop-SYSTEM/mapred/local/taskTracker/jobcache/job_201005020105_0001/attempt_201005020105_0001_m_02_0/work/tmp
does not
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.
