					| Hmm, that issue must have been introduced as part of a recent change. Can you share your program so we can reproduce abs fix the bug? Am 24.06.2015 16:56 schrieb "Flavio Pompermaier" <[hidden email]>:

					| Hi, is it possible to get a smaller version of that program that reproduces the bug or give a few more details about the structure of the job?Without any hints, it is very hard to reproduce and fix the bug. 2015-06-24 18:23 GMT+02:00 Flavio Pompermaier <[hidden email]>:

					| Also, can you open a JIRA for the issue? Otherwise it might get lost on the mailing list.Thanks you! 2015-06-30 10:56 GMT+02:00 Fabian Hueske <[hidden email]>:

Hi yesterday on the union I faced an other problem:
 at runtime it was saying something like “Union cannot work with dataset of two different types” then it was showing the types and they were exactly the same (Tuple5<Long, String, Long, Long, MyClass> I solved it changing on field of the tuple from a custom object (MyClass) that was containing only a double to a native double and it worked I don’t know if it is related but it may be Michele
