{code}
They way I connect: 
{code}
def f(path:Path): Boolean = {
      !path.getName.contains("tmp")
    }

 val client_log_d_stream = ssc.fileStream[LongWritable, Text, TextInputFormat](input_folder,
f _ , newFilesOnly = false)
{code}

Nothing is processed. Than I add file to directory and it processes it. But not the old ones

> newFilesOnly does not work according to docs.

says, that it shouldn't work as expected.

not clear at all in terms, what code tries to do
