We probably should not be configuring xcom settings from the hook in this way but for better or worse we've done it, first in apache#26766 and again in apache#28125. The problem is that other operators derived from KPO, e.g. GKEStartPodOperator, may use a different hook that doesn't have this xcom-specific methods. So KPO needs to tolerate that.

There was a problem hiding this comment.
- I think that it would be better to replace these two
ifstatements with oneif isinstance(self.hook, GKEPodHook). For the long term, maybe we should consider refactoring the abstraction. - Is it possible to unit test it? If so, it would be nice to implement.
