Scheduling Weekly Oozie

There is not (in the 3.3.2 source i'm looking at), but there's nothing stopping you from downloading the source and amending the core/java/org/apache/oozie/coord/CoordELEvaluator.java file, specifically the createURIELEvaluator(String) method:

public static ELEvaluator createURIELEvaluator(String strDate) throws Exception {    ELEvaluator eval = new ELEvaluator();    Calendar date = Calendar.getInstance(DateUtils.getOozieProcessingTimeZone());    // always???    date.setTime(DateUtils.parseDateOozieTZ(strDate));    eval.setVariable("YEAR", date.get(Calendar.YEAR));    eval.setVariable("MONTH", make2Digits(date.get(Calendar.MONTH) + 1));    eval.setVariable("DAY", make2Digits(date.get(Calendar.DAY_OF_MONTH)));    eval.setVariable("HOUR", make2Digits(date.get(Calendar.HOUR_OF_DAY)));    eval.setVariable("MINUTE", make2Digits(date.get(Calendar.MINUTE)));    // add the following line:    eval.setVariable("WEEK", make2Digits(date.get(Calendar.WEEK_OF_YEAR)));    return eval;}

You should then be able to follow the instructions to recompile oozie

I would note that you should be weary of how week numbers and years don't always fit together nicely - for example week 1 of 2013 actually starts in 2012:

As produced by the following test snippet:

@Testpublic void testDates() {    Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("UTC"));    cal.set(2012, 11, 25);    for (int x = 0; x < 15; x++) {        System.err.println(cal.getTime() + " : " + cal.get(Calendar.YEAR)                + " W " + cal.get(Calendar.WEEK_OF_YEAR));        cal.add(Calendar.DAY_OF_YEAR, 1);    }}
