> @Hexiaoqiao Yes, this can happen. This is expected, since the concurrency is configured to a low value, which increases checkpoint execution time. In this scenario, we should set the parallelism to 3 rather than simply matching the number of remote NNs. (Using 7 parallel threads is too high and unnecessary, This is also the main problem that this patch aims to solve) Got it. However we have changed the configuration `dfs.namenode.checkpoint.period` logic here, I think we need tell the truth to end users when release at least.
