2.mkdir /tmp/test; cp job-v1.yaml job-v2.json /tmp/test;cd /tmp/test
3.oc convert -f .
4.oc convert -f . | oc create -f -

Actual results:
3.All files are converted
4.Only one resource is created
$ oc convert -f . | oc create -f -
running in local mode...
scheduledjob "hello" created

Expected results:
4. Both job "pi" and scheduledjob "hello" should be created successfully
