Work Description: adejanovski commented on issue #5124: [BEAM-3485] Fix
split generation for Cassandra clusters
URL: https://github.com/apache/beam/pull/5124#issuecomment-381138950
Hi @iemejia, I was actually working on BEAM-4049 when I noticed that split
generation was broken.
Since I could tackle it in a very short time, that there didn't seem to be
activity on the ticket and that the tickets seem to be assigned automatically
upon creation, I assumed it was ok to send a PR.
I'll follow your guidelines in the future and get a green light before
working on existing tickets.

> As the question author points out, the error is likely that token($pk) should
> be token(pk). This was likely masked by BEAM-3424 and BEAM-3425, and the
> splitting code path effectively was never invoked, and was broken from the
> first PR - so there are likely other bugs.
> When testing this issue, we must ensure good code coverage in an IT against a
> real Cassandra instance.
