Description

1. define a workflow with credentials section
2. define a MR action
3. followed by a Hive Action with cred tag (kerberos enabled for metastore)

Workflow execution fails with following error:
"Could not load credentials with name [null]"

A workaround is to make all actions in the workflow take the cred tag, but this will break existing workflows cause backward compatibility issue.

It looks like OOZIE-2446 surfaces this underlying dormant issue.
