Set 'Empty filter placeholder' in views config
Looks to be grabbing the value from the wrong place.
Line 128 of data tables.module
$datatable_options['sFilterColumnsPlaceholder'] = $options['['filter_columns_placeholder'];
Should be changed to
$datatable_options['sFilterColumnsPlaceholder'] = $options['filter_columns']['filter_columns_placeholder'];
Here is the printed array of $options that reference
Array
(
[grouping] => Array
(
)
....
....
[filter_columns] => Array
(
[filter_columns_placeholder] => Search...
[name] => thead_input
[field_stem_occupations_text] => thead_input
)
[filter_columns_placeholder] => - Filter -
)
Here you can see we have two different filter_columns_placeholder values and it seems views sets ['filter_columns']['filter_columns_placeholder'] but code is looking at [filter_columns_placeholder] which is still '- Filter -'.

Also looks like line 206 of DataTables.php also needs an update so views pulls from the correct place.
'#default_value' => $this->options['filter_columns_placeholder'],
should be
'#default_value' => $this->options['filter_columns']['filter_columns_placeholder'],
