How to use oozie to find data path in HDFS with uncertain date

Question

I have a Hive table partitioned by date(e.g. 20150730)

Furthermore, I created a hive query which consumes today's partition date and the most recent previous partition date which is not necessary to be yesterday. (e.g. 20150730 and 20150728)

I want to use oozie to execute this hive query daily, but how can I find the previous partition date? (again the previous proportional date is unpredictable)

请检查，您可能需要在提及示例中应用一些修改。

正如你所说，日期是不可预测的，但相信它应该是格式

你也可以试试像

self.numlabel.text = @"2";

即使它没有预测，这些也会给你以前的日期......
