How to set current month, day or year as workflow parameter in a coordinator (on Hue)

I have a Oozie workflow which has three parameters that expect a day, month and year respectively. This workflow works perfect with manual input. I am now looking for a coordinator which daily runs this workflow and automatically fills in these parameters with the current day, month and year.

I already tried ${DAY}, ${MONTH} and ${YEAR} which Hue seemed to propose but I get the following error when submitting the coordinator with e.g. ${MONTH} as value for my month parameter.

E1004: Expression language evaluation error, Unable to evaluate :${MONTH}:

I am trying this on CDH 5.8.

Solution

  • I found the answer myself with something Hue also suggested to me. So ${DAY}, ${MONTH} and ${YEAR} were not the way to go.

    The following values however did solve my question:

    ${coord:formatTime(coord:nominalTime(),'dd')}

${coord:formatTime(coord:nominalTime(),'MM')}

${coord:formatTime(coord:nominalTime(),'yyyy')}
