> Key: BEAM-7658
> URL: https://issues.apache.org/jira/browse/BEAM-7658
> Project: Beam
> Issue Type: Bug
> Components: testing
> Reporter: Lukasz Gajowy
> Priority: Major
>
> This came out while creating KafkaIOIT ingesting data generated using
> SyntheticUnboundedSource. Hashcode of data created by
> {code:java}
> .apply("Calculate hashcode", Combine.globally(new
> HashingFn()).withoutDefaults()){code}
> was different for 1000 records every time. When a number of splits was set to
> 1 the problem disappeared (sourceOptions.forceNumInitialBundles).
