OOZIE-129: fs action should allow free order of sub-elements
------------------------------------------------------------

                 Key: OOZIE-546
                 URL: https://issues.apache.org/jira/browse/OOZIE-546
             Project: Oozie
          Issue Type: Bug
            Reporter: Angelo K. Huang
            Assignee: Angelo K. Huang


According to the xsd [1],
You can use as many commands as you want in the fs action node, but the problem is that they have defined the commands within an xs:sequence tag, which means the commands can be used only in a particular order. According to the xsd, the sequence of the action has to be delete, mkdir, move and chmod. This implies that you cannot have an mkdir after move :-/.

I don't particularly understand the reasoning behind why it is defined as an xs:sequence though.

I think the XSD is written in a very rigid form. The user needs to follow that order. However, we should relax the constraint  by allowing any ordering. We could use "xs:choice" in XSD and need to make sure that in the execution order too.
