Work Description: aaltay commented on issue #9811: [BEAM-8402] Create a
class hierarchy to represent environments
URL: https://github.com/apache/beam/pull/9811#issuecomment-578000835
Beam 2.18 broke some users. Reverting back to 2.17 resolves the issues. I
believe this PR is the root cause. I am trying to get more information to file
a JIRA.
A stack trace I got looks like this:
```

if obj not in self._obj_to_id:

```
I am suspecting this is related to the changes in the Environment class.
@violalyu @chadrik or other reviewers, do you know what this might be about?

> As a first step towards making it possible to assign different environments
> to sections of a pipeline, we first need to expose environment classes to the
> pipeline API. Unlike PTransforms, PCollections, Coders, and Windowings,
> environments exists solely in the portability framework as protobuf objects.
> By creating a hierarchy of "native" classes that represent the various
> environment types -- external, docker, process, etc -- users will be able to
> instantiate these and assign them to parts of the pipeline. The assignment
> portion will be covered in a follow-up issue/PR.
