Closes #178
Fixes #338

TODOs

  • Release new Hadoop image with openssl and Kerberos clients use in docs and tests
  • Release and use operator-rs change
  • Fix hardcoded kinit nn/simple-hdfs-namenode-default.default.svc.cluster.local@CLUSTER.LOCAL -kt /stackable/kerberos/keytab in entrypoints
  • Go through all hadoop settings and see if they can be improved

Mostly LGTM in theory, a few nits and haven't tested it yet.

# Tribute to https://github.com/Netflix/chaosmonkey

# We need to force-delete the Pods, because IONOS is sometimes unable to delete the pod (it's stuck in Terminating for > 20 minutes)

That's worrying... do we have access to IONOS' kubelet logs? Is this an IONOS-only issue?

Have to admit I'm not sure if we have access to the kubelet logs. Test passed on Azure however

Update: Support recommended using https://github.com/kvaps/kubectl-node-shell, which worked.
Sadly it only logs stuff during startup and than remains silent.

journalctl -u kubelet --since "48 hour ago"
-- Logs begin at Sat 2023-06-03 19:51:35 UTC, end at Tue 2023-06-06 12:01:05 UTC. --
-- No entries --

Anyway, even with force deletion tests have random timeouts on IONOS after we added the chaosmonkey. Everything is really slow

Waiting for integration tests to complete, but LGTM otherwise.

We'll probably want to note this in the changelog though?

All that and I forgot the CHANGELOG :D
Thanks for your review and work + help on Kerberos overall!

I have 4 testclusters running since this morning, let's wait some time with merging to see if they survive

All 4 clusters are still healthy, merging this
