Hi Yehia ,
One of the possible reasons are that the jar and the code being debugged is
not in sync. Or the line where the debug point is put is actually not reached.
Apart from the above i am not sure of your scenaro which you want to debug, so
i will not be able to take a guess !

Subject: Re: ResourceManager debugging
Hi Naga,
Thanks a lot for your help. I have submitted multiple MapReduce jobs, the
debugger is attached successfully to eclipse and I put a breakpoint in
org.apache.hadoop.yarn.server.resourcemanager.ResourceManager, but, eclipse
debugger still waits without any interruption. However, I put another
breakpoint in another class (for example RMAppAttemptContainerAllocatedEvent),
the debugger reached the code. Do you have any idea why ResourceManager code
was not reachable by the debugger?
Thanks

YARN_RESOURCEMANAGER_OPTS="$YARN_RESOURCEMANAGER_OPTS -Xdebug

Subject: ResourceManager debugging
Hi,
I am wondering how to remote debugging Yarn's RM using eclipse. I tried to
adding the debugging options "-Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=1337" to YARN_OPTS but
it did not work. Any suggestions ?
Thanks
