>
> Currently, `hbase-daemon.sh` supports commands like `start`, `stop`, and
> `restart`, but lacks a `status` command to check whether a given HBase
> component (e.g., master or regionserver) is running.
> As a result, operators and automation tools must rely on external utilities
> such as `jps`, `ps`, or `lsof` to infer the process status — often parsing
> command output manually, which can be error-prone or inconsistent across
> environments.
> This patch adds a `status` subcommand to `hbase-daemon.sh`.
>
> h1. Benefits
> * Enables easy integration with tools like Ansible, systemd, Kubernetes
> probes, and custom scripts
> * Makes health checking and restart logic simpler and more consistent
> * Removes the need for workaround scripts involving `jps` or `ps -ef | grep
> hbase`
> * Aligns with standard behavior of other Unix-style service scripts
