-------------------------------------
[~mladenkov] can you please put {{coordinator.xml}}, {{workflow.xml}}, and
{{job.properties}} details here? Much appreciated.
> Add toInteger() basic EL function
> ----------------------------------
>
> Key: OOZIE-3140
> URL: https://issues.apache.org/jira/browse/OOZIE-3140
> Project: Oozie
> Issue Type: New Feature
> Components: workflow
> Affects Versions: 4.3.0
> Reporter: Mladen Kovacevic
> Priority: Minor
>
> The set of Basic EL Functions described in the docs section 4.2.2 should be
> extended to include a basic function called toInteger(). This is useful so
> that we can define parameters in the properties files that we can easily
> convert from String to Integer to pass into functions that accept int as
> input parameters.
> For example, many of the Dataset or Date EL functions take 'int' as input,
> such as coord:dateOffset [1], coord:offset [2] and certainly numerous others.
> Currently, any parameter defined in the job properties file is considered a
> String, and can not be used out of the box as an input parameter to these
> functions.
> Having a simple toInteger() function can help simplify this.
