> Have we observed any changes in CPU usage after adding this metric? I noticed that the collection frequency is set to once per second. I refer to YARN-10771 to set the interval time. > I have some doubts that network congestion could be the cause of this issue. Is the number of tcp connections normal? I checked the two machines with this problem in the cluster, and there was no obvious abnormality at the network level, and the number of connections did not fluctuate too much. ipc.Client has no timeout option in synchronous mode, so NM's AsyncDispatcher has been waiting here. -- This is an automated message from the Apache Git Service.
