Reproduce the issue with ./sbin/start-cli.sh and the load '/mntb/iotdb/data' verify=false onSuccess=none command using the reported versions. Observe the datanode Java process after loading completes and investigate the load path and CPU behavior. Done means CPU usage returns to normal after a successful load.
