> 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.
