Repos with getting started examples:

[!NOTE] @razvan: _there is a getting_started.sh script that you should be able to run and .... it should just work (tm)_

The HDFS one fails, but I'm not too sure why:

❯ kubectl exec -n default webhdfs-0 -- curl -s -XGET "http://simple-hdfs-namenode-default-0:9870/webhdfs/v1/testdata.txt?user.name=stackable&op=CREATE&noredirect=true"
command terminated with exit code 6

@razvan is working on it in https://github.com/stackabletech/hdfs-operator/pull/492

The Hive one fails because it uses old stackablectl CLI args:

error: unexpected argument '--additional-stacks-file' found

A note for anyone in future for how I ran the tests:

# Some of the scripts are in a code/ subdirectory
# pushd docs/modules/superset/examples/getting_started
# pushd docs/modules/superset/examples/getting_started/code
pushd $(fd -td getting_started | grep examples); cd code 2>/dev/null || true

# Make a fresh cluster (~12 seconds)
kind delete cluster && kind create cluster
./getting_started.sh stackablectl

# Make a fresh cluster (~12 seconds)
kind delete cluster && kind create cluster
./getting_started.sh helm

popd

Also, the kafka-operator script uses kafkacat, and if you use nix (eg: nix-shell -p kafkacat, the binary is called kcat, so the script needs adjusting.
