> Looking at the {{Driver#runInternal(String command, boolean
> alreadyCompiled)}}:
> {code}
> HiveDriverRunHookContext hookContext = new
> HiveDriverRunHookContextImpl(conf, command);
> // Get all the driver run hooks and pre-execute them.
> List<HiveDriverRunHook> driverRunHooks;
> {code}
> The context is initialized with the {{command}} passed in to the method.
> However, this command is always null if {{alreadyCompiled}} is true, which is
> the case for HS2 mode.
