RE: ResourceManager debugging
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 ! Regards, Naga Huawei Technologies Co., Ltd.

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?
