Subject Re: Debugging DFS and MapReduce through Eclipse
Date Wed, 24 May 2006 16:00:30 GMT
I debug using eclipse. For example, if I need to debug JobTracker, I  
put the following lines in the hadoop script:

elif [ "$COMMAND" = "jobtracker" ] ; then

the I just start everything up using start-all.sh. I should note that  
I always debug code built inside of eclipse. I don't use ant. I just  
import Java projects from SVN and export JAR files.
