Exception when deleting namespaced pod

[pires]

Running Kubernetes 1.9.1 and a snapshot build of this repo as of 505a812, I get this when deleting a namespace pod:

This is know issue #86 (comment)
This error may arise for all delete K8 objects.
as said in comment, you may wrap it in try catch.

Thank you!

Another option may be:

final Response response = apiClient.deleteNamespacedPodCall(pod.getMetadata().getName(), pod.getMetadata().getNamespace(), new V1DeleteOptions().gracePeriodSeconds(0L).propagationPolicy("Foreground"), null, null, null, null, null, null).execute();

if (!response.isSuccessful()) {
    LOGGER.warn("Couldn't delete pod [{}] with reason: {}", pod.getMetadata().getName(), response.message());
}

Closing as a dup of #86

[icehehehe]

Another option may be:

final Response response = apiClient.deleteNamespacedPodCall(pod.getMetadata().getName(), pod.getMetadata().getNamespace(), new V1DeleteOptions().gracePeriodSeconds(0L).propagationPolicy("Foreground"), null, null, null, null, null, null).execute();

if (!response.isSuccessful()) {
    LOGGER.warn("Couldn't delete pod [{}] with reason: {}", pod.getMetadata().getName(), response.message());
}

This is very useful.I use the newest java-client with the parameter modified.Thank you! ! !
