Subject debugging of map reduce tasks
Date Tue, 28 May 2013 13:17:28 GMT

sorry, just a beginners question...

I'm trying to debug a simple Map/Reduce task (MaxTemperature example in 
"Hadoop The definite guide")

My understanding: within a standalone distribution it should be possible 
to debug even the Map and Reduce tasks.

I found some descriptions for Eclipse as well as for Intellij

Personally I'm working with intellij

I can start the task, I get a correct result but the process doesn't 
stop in the Mapper or Reducer even with breakpoints. I use the old and 
new API

Thanks for some hints!
