Github user nchammas commented on the issue: https://github.com/apache/spark/pull/14579 > So there is no chaining requirement, and it will only work in a with statement. @MLnick - Couldn't we also create a scenario (like @holdenk did earlier) where a user does something like this? ```python persisted_rdd = persisted(rdd) persisted_rdd.map(...).filter(...).count() ``` This would break pipelining too, no? And I think the expectation would be for it not to break pipelining, because existing common context managers in Python don't have a requirement that they _must_ be used in a `with` block. For example, `f = open(file)` works fine, as does `s = requests.Session()`, and the resulting objects have the same behavior as they would inside a `with` block.
