TextNode cannot be cast to ObjectNode

[tprus]

There is problem with parsing YAML config with JSON element like that:

apiVersion: v1
data:
  staging.json: |
    {
      "type": "service_account",
      ...
    }

It throws error:

java.lang.ClassCastException: com.fasterxml.jackson.databind.node.TextNode cannot be cast to com.fasterxml.jackson.databind.node.ObjectNode
	at io.fabric8.kubernetes.internal.KubernetesDeserializer.deserialize(KubernetesDeserializer.java:73)
	at io.fabric8.kubernetes.internal.KubernetesDeserializer.deserialize(KubernetesDeserializer.java:32)
	at com.fasterxml.jackson.databind.ObjectMapper._readMapAndClose(ObjectMapper.java:4001)
	at com.fasterxml.jackson.databind.ObjectMapper.readValue(ObjectMapper.java:3079)
	at io.fabric8.kubernetes.api.KubernetesHelper.loadYaml(KubernetesHelper.java:513)

The purpose of that part is to be able to pipe json file so when we mount the configmap we can have a json file with the content from it.

It is well documented in kubernetes
https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-configmap/#create-configmaps-from-directories

I'm able to apply it manually using kubectl apply -f

what about this issue? is it solved?

[shawkins]

No longer occurs on latest. Not sure when it was actually addressed.

Probably fixed by #2646 (#2510). We are doing two passes now to deserialize YAML. Snakeyaml is used first/instead since there were a few issues with Jackson.
