Hej, The data set I'm working on is quite large so I created a pojo class for it to make it less messy. I want do do a simple map, group reduce job. But the groups needs to be sorted on a secondary key.
>From what I understand I would get that by doing: dataset.groupBy( key1 ).sortGroup( key2 , Order.ASCENDING ) Is that correct? And if so how do I do the same call using a KeySelector. While groupBy can take a KeySelector sortGroup cant. Also can someone explain to me what Order.ANY is about? cheers Martin
