I modified my local copy of storm.py to make it log the contexts its
received and I noticed that `TesterSpout` gets:
```python
{u'task->component':
{u'20': u'__acker',
u'21': u'__acker',
u'22': u'__acker',
u'1': u'1',
u'3': u'__acker',
u'2': u'2',
u'5': u'__acker',
u'4': u'__acker',
u'7': u'__acker',
u'6': u'__acker',
u'9': u'__acker',
u'8': u'__acker',
u'11': u'__acker',
u'10': u'__acker',
u'13': u'__acker',
u'12': u'__acker',
u'15': u'__acker',
u'14': u'__acker',
u'17': u'__acker',
u'16': u'__acker',
u'19': u'__acker',
u'18': u'__acker'},
u'sources->grouping': {},
u'stream->target->grouping': {u'default': {u'2': u'SHUFFLE'}},
u'streams': [u'default'],
u'stream->outputfields': {u'default': [u'word']},
u'taskid': 1,
u'componentid': u'1'}
```
and the corresponding `TesterBolt` gets:
```python
{u'task->component':
{u'20': u'__acker',
u'21': u'__acker',
u'22': u'__acker',
u'1': u'1',
u'3': u'__acker',
u'2': u'2',
u'5': u'__acker',
u'4': u'__acker',
u'7': u'__acker',
u'6': u'__acker',
u'9': u'__acker',
u'8': u'__acker',
u'11': u'__acker',
u'10': u'__acker',
u'13': u'__acker',
u'12': u'__acker',
u'15': u'__acker',
u'14': u'__acker',
u'17': u'__acker',
u'16': u'__acker',
u'19': u'__acker',
u'18': u'__acker'},
u'sources->grouping': {},
u'stream->target->grouping': {},
u'streams': [u'default'],
u'stream->outputfields': {u'default': [u'word']},
u'taskid': 2,
u'componentid': u'2'}
```
`stream->target->grouping` seems to be working fine, but for some reason
`TesterSpout` isn't showing up in `sources->grouping` (as I would expect it to,
since its the source for `TesterBolt`). Let me fix that.
