> URL: https://issues.apache.org/jira/browse/HBASE-26951
> Project: HBase
> Issue Type: Bug

> Affects Versions: 3.0.0-alpha-2

>
> 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.
