I might have run into stackabletech/hdfs-operator#686 during development. I recognized that I can have an empty string in my discovery configMap from time to time. Behaviour appears to be flaky, but yet more often then not the emtpy string appears: ExpectedFlaky faulty one |

This should probably be called listener, as it isn't a ref.
Suggested change

All other fields use fragment_attr, is that needed here too?
Suggested change

Also, do we want the String::default() to be called? Doesn't it have to be a valid class, or it falls back to cluster-internal?

also outdated I think.
Yes, now it falls back to cluster-internal if listenerClass is not given.

Would this cause a collision if there are multiple role groups defined?

Also outdated as it's on role level now

I would split the pdbs and listener stuff like so:
let role_config = hive.role_config(&hive_role);
if let Some(HiveMetastoreRoleConfig {
common: GenericRoleConfig {
pod_disruption_budget: pdb,
},
..
}) = role_config
{
add_pdbs(pdb, hive, &hive_role, client, &mut cluster_resources)
.await
.context(FailedToCreatePdbSnafu)?;
}
// std's SipHasher is deprecated, and DefaultHasher is unstable across Rust releases.
// We don't /need/ stability, but it's still nice to avoid spurious changes where possible.
let mut discovery_hash = FnvHasher::with_key(0);
if let Some(HiveMetastoreRoleConfig { listener_class, .. }) = role_config {
let group_listener: Listener =
build_group_listener(hive, &resolved_product_image, &hive_role, listener_class)?;
let listener = cluster_resources
.add(client, group_listener)
.await
.context(ApplyGroupListenerSnafu {
role: hive_role.to_string(),
})?;
for discovery_cm in discovery::build_discovery_configmaps(
hive,
hive,
hive_role,
&resolved_product_image,
None,
listener,
)
.await
.context(BuildDiscoveryConfigSnafu)?
{
let discovery_cm = cluster_resources
.add(client, discovery_cm)
.await
.context(ApplyDiscoveryConfigSnafu)?;
if let Some(generation) = discovery_cm.metadata.resource_version {
discovery_hash.write(generation.as_bytes())
}
}
}

NoNodePort, FindEndpoints, InvalidNodePort etc. unused
