> With FLINK-13184, we replaced the {{NMClient}} with the {{NMClientAsync}}. As part of this change, container start up errors are now handled by a callback to {{NMClientAsync.CallbackHandler}}. The implementation of {{NMClientAsync.CallbackHandler#onStartContainerError}} will be called by the {{NMClientAsync}}. Since the implementation does state changing operations, it needs to happen inside of the {{YarnResourceManager}} main thread.
