How to use a Oozie job property in a Oozie workflow EL function?

In my Oozie workflow, this is how a file is passed as a command line argument for a Java action:

<file>${concat(filesPath, 'config.properties')}</file>

While this works fine for a coordinator run, it has a problem when run manually through HUE like in this video -- 'filesPath' does not show up as a parameter in the dialog box that HUE throws up to take parameters.

I tried

 ${concat(${filesPath}, 'config.properties')}  and 
 ${concat(wf:conf(filesPath), 'config.properties')}

First throws syntax error and second returns/concats empty value.

I am basically looking for a way to declare a parameter/job property in an Oozie Workflow EL function so that it works both for a Coordinator run and also for a manual run from HUE (should show a text box to enter value)

Solution

  • I ended up doing it like this:

    <file>${additionsPath}config.properties</file>

    This would work only with the 'concat' EL function though.
