- Replace stackable-operator `print_startup_string` with `tracing::info!` with fields.
- BREAKING: Inject the vector aggregator address into the vector config using the env var `VECTOR_AGGREGATOR_ADDRESS` instead
of having the operator write it to the vector config ([#551]).
- Document that Spark Connect doesn't integrate with the history server ([#559])

The example above adds a new endpoint for application metrics.

== Spark History Server

Unforunately integration with the Spark History Server is not supported yet. The connect server seems to ignore the `spark.eventLog` properties while also prohibiting clients to set them programatically.

== Notable Omissions

The following features are not supported by the Stackable Spark operator yet

* Integration with the Spark History Server.
* Authorization and authentication. Currently, anyone with access to the Spark Connect service can run jobs.
* Volumes and volume mounts can be added only with pod overrides.
* Job dependencies must be provisioned as custom images or via `--packages` or `--jars` arguments.
