Hi all,

I can successfully debug the MapReduce Applicatio= nMaster in standalone mode by launching the pi estimator example with this = command:

hadoop jar hadoop-mapreduce-e= xamples-3.0.0-SNAPSHOT.jar pi "-Dyarn.app.mapreduce.am.command-opts=3D= -Xdebug -Xrunjdwp:transport=3Ddt_socket,server=3Dy,suspend=3Dy,address=3D80= 00" 10 10

and then attaching a debugger to port= 8000 using Eclipse. This doesn't work with the DistributedShell exampl= e, presumably because it's not configurable with yarn.app.mapreduce.am.= command as it's not MapReduce. Looking in yarn-default.xml, I don't= see an equivalent parameter. For learning purposes, how can I debug the Di= stributedShell example (and other AMs)?

Thanks!
