I'm surprised that there are only a few changes required for this! It's better than I thought :-) I have only one small minor request, LGTM otherwise.

Perhaps we could have another conditional here, setting the strategy to allInOne if it's all-in-one? This way, we don't break current CRs using strategy=all-on-one. We could possibly log a WARN, stating that all-in-one is deprecated in favor of allInOne.

Looks like the coverage went down. Would you mind checking what's missing?

[jpkrohling]

Just a small typo on the new test, otherwise. One thing we could do to not break compatibility with older CRs is to duplicate the spec entries for CassandraCreateSchema and AllInOne.

I'm not sure it's worth at this point, but it's something else to consider in the future (apart from creating a new spec version, like v1alpha2)

Done, thanks!

@jpkrohling Agree. We need to decide when the operator is stable enough to start maintaining backward compatibility and using spec version to make significant changes. We should also do a release soon and document the breaking changes.

[jpkrohling]

Sorry for the last minute change, but I think I found a possible bug that would be introduced by this change involving ToLower.

	// check for incompatible options

	if strings.ToLower(jaeger.Spec.Storage.Type) == "memory" && strings.ToLower(jaeger.Spec.Strategy) != "allInOne" {

I missed this before: the second part will never match, as the right-hand side comparison is lowering the case for the strategy but uses upper case in the constant. In other words, ToLower("allInOne") will never be equal to "allInOne".

I guess we need a new test :)
