-----------------------------------------------
This test started to fail (but not locally). I see it in CircleCI as well as in
pre-ci.

However I do not think this patch is the cause of that. It also fails on other
patches too. I do not know what's up because the last time we touched something
related to compression was CASSANDRA-20938 (CQLSSTableWriter can produce
SSTables backed by dict) and there it did not fail:

> Add Nodetool command to import / export/ list compression dictionary
> --------------------------------------------------------------------
>
> Key: CASSANDRA-20941
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20941
> Project: Apache Cassandra
> Issue Type: New Feature
> Components: Tool/nodetool
> Reporter: Yifan Cai
> Assignee: Stefan Miklosovic
> Priority: Normal
> Time Spent: 8h 40m
> Remaining Estimate: 0h
>
> Introduce a new nodetool command to import a ZSTD compression dictionary.
> - Imported dictionary is automatically promoted as the current dictionary
> without going through evaluation.
> - Intended as an administrative tool; usage should be documented with
> warnings about its impact.
