Hi Lasse

Never meet this problem before, but can you share some exception stack trace so that we could take a look. The simple project to reproduce is also a good choice.

Subject: Latency tracking together with broadcast state can cause job failure

 

Hi

We have in both Flink 1.9.2 and 1.10 struggled with random deserialze and Index out of range exception in one of our job. We also get out of memory exceptions.
We have now identified it as a latency tracking together with broadcast state Causing the problem. When we do integration testing locally we don’t see any problem it’s only fails running on the cluster.
We have concluded that latency tracking package send over broadcast cause the data stream to be corrupted and causing the exceptions.
We work on preparing a simple project on github to reproduce the problem so the underlying problem can be solved.

Anyone else have seen these kind of problems?

Med venlig hilsen / Best regards
