No, haven't looked at it since my last mail :-( Both plans (with and without forward fields annotation) look good except for the suspicious pipeline breaker. @Vasia Could you open a JIRA and assign it to me? I'll have a closer look and try to figure out what's going on. 2015-04-27 10:34 GMT+02:0

I think Fabian looked into this a while back... @Fabian, do you have any insights what causes this? On Sat, Apr 25, 2015 at 7:46 PM, Vasiliki Kalavri wrote: > Hi, > > I actually ran into this problem again with a different algorithm :/ > Same exception and it looks like getMatchFor() in Compac

Hi, I actually ran into this problem again with a different algorithm :/ Same exception and it looks like getMatchFor() in CompactingHashTable returns a null record. Not sure why or why the annotation prevents this from happening. Any insight is highly welcome :-) Shall I open an issue so that we

Thanks for the nice setup! I could easily reproduce the exception you are facing. But that's the only good news so far :-( I checked the plans and both are valid and should compute the correct result for the program. The split-of solution set delta is required because the it needs to be repartitio

Hi Fabian, I am using the dblp co-authorship dataset from SNAP: http://snap.stanford.edu/data/com-DBLP.html I also pushed my slightly modified version of ConnectedComponents, here: https://github.com/vasia/flink/tree/cc-test. It basically generates the vertex dataset from the edges, so that you do

That looks pretty much like a bug. As you said, fwd fields annotations are optional and may improve the performance of a program, but never change its semantics (if set correctly). I'll have a look at it later. Would be great if you could provide some data to reproduce the bug. On Apr 3, 2015 12:

NullPointerException in DeltaIteration when no ForwardedFileds annotation

2015-04-03 Thread Vasiliki Kalavri
Hello to my squirrels, I've been getting a NullPointerException for a DeltaIteration program I'm trying to implement and I could really use your help :-) It seems that some of the input Tuples of the Join operator that I'm using to create the next workset / solution set delta are null. It also see
