Stefan Richter resolved FLINK-10860.
------------------------------------
Resolution: Not A Problem
Problem is most likely in the Beam code, where serializers are duplicated with
shared stateful objects.
> java.lang.ArrayIndexOutOfBoundsException Error reading state
> ------------------------------------------------------------
>
> Key: FLINK-10860
> URL: https://issues.apache.org/jira/browse/FLINK-10860
> Project: Flink
> Issue Type: Bug
> Components: Core, State Backends, Checkpointing
> Reporter: JC
> Priority: Major
>
> We have a pipeline running on Flink 1.5.4 cluster for while, using Apache
> Beam as an abstraction layer.
> This pipeline have multiple windows and operations and during our deployment
> we always include in the flink run command '*--allowNonRestoredState
> --fromSavepoint=......*', our savePoint and state are stored on HDFS.
>
> Today we got the following exception few minutes after deployment:
> {{java.lang.RuntimeException: Exception occurred while processing valve
> output watermark: }}
