#Coding style

1. get consistent: most of your functions and variable names are lower_snake_case except `direcToData` (why not `directToData`?), you should stick to lower_snake_case which is recommended by PEP8.

<!-- ol/ul separator -->

* get consistent: you should have spacing around all your affectations (`=`).
* use `except ValueError as e:`, the form using a coma is being deprecated and a syntax error in Python 3;
* use `pass` instead of `{}` to create a no-op statement;
* try to be consistent: indent with 4 spaces anywhere, not 9 as in your `except`;
* `myloop` (why not `my_loop`?) is set to `True` and never changed, thus `if myloop` is unnecessary;
* two blank lines better separate functions and classes visually. But within the same block it feels weird, you should remove one between `pool =` and `direcToData =`.

Oh, and you use both `'` and `"` as string delimiter. You should try to use only one for consistency.

#Directory traversal

You may be able to simplify your file management using `os.walk`. If `"/FullData/RowData"` recursively contains only the files you which to process, then you can write:

    for path, dirnames, filenames in os.walk('/FullData/RowData'):
        if filenames: # files exist in traversed directory
            full_names = map(lambda f, path=path: os.path.join(path, f), filenames)
            pool.map(process_file, full_names, 16) # Using @holroy advices

The `process_file` function would then be:

    def process_file(filename):
        producer = SimpleProducer(client)
        with open(filename) as source_file:
            for line in source_file:
                try:
                    jrec = json.loads(line.strip())
                    producer.send_messages('twitter2613', json.dumps(jrec))
                except ValueError: # `as` nothing since we don't use the value
                    pass

This will also help process things faster since it will create only one producer per file instead of one per line.
