Normal Description
Today our CI images at Apache Airflow started to fail , and when we investigated, the root cause seems to be that Cassandra 3.0 image in our CI jobs failed to start (and pass health checks). Usually we have one of our tests bring up a number of images via docker compose and we used "cassandra:3.0" image for that. We noticed 3.0.26 was released 15 hours ago so this is almost for sure some 3.0.25 -> 3.0.26 difference.
The whole tests fails because cassandra container is unhealthy:

The errors from the cassandra container do not show anything suspicious:

Our docker-compose entry is here:

Basically - we run healthcheck that checks if cassandra is up and this health check worked fine before, but seems to fail now. It's either we are using wrong healthcheck or there is some bug in the command ?:
healthcheck:
test: "[ $$(nodetool statusgossip) = running ]"
interval: 5s
timeout: 30s
retries: 50
restart: always
We mitigated it by switching to 3.0.25 temporarily https://github.com/apache/airflow/pull/23522
Is this an error in cassandra? Or should we maybe change our health-check command?
