Description

Since ShutdownHook is not registered at startup, when HMaster is stopped through hbase-daemon.sh, HMaster cannot exit gracefully,  the threads and services of HMaster cannot be closed normally, and the master local region also cannot be closed normally, which may lead to some inexplicable problems.
