Description XiaochuanWang 2017-07-24 09:15:32 UTC 
Description of problem:
oc debug with not-exist node, 3.5 output is clear 'Error from server (NotFound): nodes "invalidnode" not found', but 3.6 output is 'error: unable to create the debug pod "mydc-debug" on node "invalidnode"', which cannot tell clearly whether the node is an existent node that has problem "to create the debug pod", or the node name is a non-existent node

Version-Release number of selected component (if applicable):
v3.6.153

How reproducible:
Always

Steps to Reproduce:
1. $ oc run mydc --image=aosqe/hello-openshift
2. $ oc debug dc/mydc --node-name="notexist"
wait and check output

Actual results:
"""
Debugging with pod/python35-debug, original command: container-entrypoint /usr/libexec/s2i/run
Waiting for pod to start ...

Removing debug pod ...
error: unable to create the debug pod "mydc" on node "notexist"
"""

Expected results:
Message should be clear, eg. 3.5 cli output  'Error from server (NotFound): nodes "notexist" not found'
