My environment: k8s version 1.10. kubectl version 1.10
Java client library:
<dependency>
<groupId>io.kubernetes</groupId>
<artifactId>client-java</artifactId>
<version>1.0.0-beta4</version>
</dependency>
When I use "kubectl create -f xxx.yml",Deployment created successfully. But using API, get "400 Bad Request" result. No other useful message. The result of K8s API always give out so little information for debugging. :(
Following is the full yaml of my deployment.

Thanks @ewramner
setDebugging is very useful and saved my days.
According to my deployment object, the apiVersion: extensions/v1beta1
is too old. change to apiVersion: apps/v1beta2
solved the problem.
