Currently, there is only one thread pool to handle AM launch and cleanup event in ResourceManager. We found an issue in our cluster, in some cases, too many cleanup events will block AM launcher event and make it stuck for a long time. So in this PR, we divide the shared thread pool into two separated ones to handle AM event of different kinds in case that a flood events of cleanup events blocking launcher event for a long time and vice versa, which will badly decay throughput of ResourceManager. -- This is an automated message from the Apache Git Service.
