Description

Looking at the Driver#runInternal(String command, boolean alreadyCompiled):

    HiveDriverRunHookContext hookContext = new HiveDriverRunHookContextImpl(conf, command);
    // Get all the driver run hooks and pre-execute them.
    List<HiveDriverRunHook> driverRunHooks;

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.
