Description

Currently a workflow XML is the 'workflow.xml' file under the HDFS directory specified in the job property 'oozie.wf.application.path'.

This means that a given HDFS directory can have only one workflow app (the workflow.xml file).

In many cases is desirable to share configurations and binaries among multiple workflow apps.

Today this is not possible.

Proposal:

1* If 'oozie.wf.application.path' points to a HDFS directory, the workflow app is 'workflow.xml' (today's behavior)
2* If 'oozie.wf.application.path' points to an XML file in HDFS, the workflow app is the specified file path and the workflow app directory (for all resources and and binaries) is the parent directory.

This proposal preserves backwards compatibility.
