Fabian Hueske updated FLINK-2942:
---------------------------------
Description:
When visualizing a program with three {{MapPartition}} operators that branch
off from an {{OuterJoin}} operator, two of the three {{MapPartition}} operators
are not connected to the {{OuterJoin}} operator and appear to have no input.
The problem is present in FireFox as well as in Chrome. I'll attach a
screenshot.
The problem and be reproduced by executing the "Cascading for the impatient"
[TFIDF example
program|https://github.com/Cascading/Impatient/tree/master/part5] using the
[Cascading Flink Connector|https://github.com/dataArtisans/cascading-flink].
Update: It appears that the problem is non-deterministic. I ran the same job
again (same setup) and the missing connections were visualized.
