Roman Studenikin commented on SPARK-20251:
------------------------------------------
we've spent quite a lot of time investigating this already, I didn't find
anything like that in google.
this is an app without checkpoints, so the problem happens just in the middle
of run. It just fails in producing data to kafka and skips the batch.
Could you please refer to any specific cases when this behaviour is expected or
point to any docs I could read about it?
> Spark streaming skips batches in a case of failure

> Key: SPARK-20251
> URL: https://issues.apache.org/jira/browse/SPARK-20251
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.1.0
> Reporter: Roman Studenikin
>
> We are experiencing strange behaviour of spark streaming application.
> Sometimes it just skips batch in a case of job failure and starts working on
> the next one.
> We expect it to attempt to reprocess batch, but not to skip it. Is it a bug
> or we are missing any important configuration params?
> Screenshots from spark UI:
