Hey Eduardo, There is lack of docs in this area but you can certainly plug in custom EL functions and give them aliases.
Look at all the configs prefixed "oozie.service.ELService.ext.functions" in http://oozie.apache.org/docs/3.2.0-incubating/oozie-default.xml. You can create your own function that way by mapping a name to a class plus method call. The class needs to be in the Oozie deployed WAR though, so this isn't a dynamic thing. See the examples around these config entries in the link for the inbuilt definitions we carry. I'd also strongly recommend contributing back nifty EL extensions, so that its not a maintenance pain in the long run for you guys - and others can use it as well :) On Thu, Nov 15, 2012 at 12:58 AM, Eduardo Afonso Ferreira <[email protected]> wrote: > Hey, > > Is it possible to implement custom EL Functions without having to change > Oozie source code? > I did not find documentation about how to implement custom EL Functions. > Would someone throw some links my way about where I can find information on > this? > > Thank you. > Eduardo. -- Harsh J
