Review Comment:
@lianetm—I changed the logging to an `assert` that provides useful
information for troubleshooting:
```python
tp = _create_partition_from_dict(topic_partition)
assert tp in self.assignment, \
"Topic partition %s cannot be revoked from %s as it was not previously
assigned to that consumer" % \
(tp, node.account.hostname)
self.assignment.remove(tp)
```
