GH-26: add support for multiple workflow XMLs in a single HDFS directory
------------------------------------------------------------------------
Key: OOZIE-72
URL: https://issues.apache.org/jira/browse/OOZIE-72
Project: Oozie
Issue Type: Bug
Reporter: Hadoop QA
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.
