Hi, I am trying to write a hive script which is doing some summarization. There are two summarizations hourly and daily. I want to run the hourly summarization first, then check whether the current timestamp matches some value of my favour (lets say 2012-09-13 23:00:00) and run the daily summarization.
My question is, can I use the IF conditional function which is mentioned in [1]. I could not fined any examples on this. [1] https://cwiki.apache.org/Hive/languagemanual-udf.html#LanguageManualUDF-ConditionalFunctions Thanks, Amila.
