Hi Stephan, I have not change the parallelism nor the names or anything in my program. It is the same exact jar file unmodified.
I have tried uid. but I faced this "UnsupportedOperationException: Cannot assign user-specified hash to intermediate node in chain. This will be supported in future versions of Flink. As a work around start new chain at task Map." Any clues how to carry on? I am just trying to avoid the painful process of dismantling the code and test so I come closer to the cause. I just think that if I am providing the same exact jar, nothing should break. Regards, -Rami On 4 Jan 2017, at 11:19, Stephan Ewen <se...@apache.org<mailto:se...@apache.org>> wrote: Hi! Did you change the parallelism in your program, or do the names of some functions change each time you call the program? Can you try what happens when you give explicit IDs to operators via the '.uid(...)' method?
