> Issue Type: Bug
> Components: action
> Reporter: Robert Kanter
>
> We've seen issues where if you have a hive-site.xml with the Hive action or a
> sqoop-site.xml with the Sqoop action, it fails because of a name conflict
> (the action wants to write a file with the same name). We should go through
> all of the actions and look for any filenames that go into the working
> directory and try to fix these name conflicts. Here are some ideas on how to
> fix this:
> # Generate a subdir in the working directory named "oozie-<timestamp>" and
> put all files generated by the action in there; it would be extremely
> unlikely for the user to have a directory named that.
> # Before creating any files in the action, we check if that file already
> exists and if so, rename it
> # Add "-<timestamp>" to the filenames generated by actions
> I think option 1 is the easiest and best for maintainability. We can make
> some helper method that all of the actions can use that returns the directory
> that's created and just make sure to put any created files in there.
