key when using closure
[ https://issues.apache.org/jira/browse/FLINK-10961?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chesnay Schepler updated FLINK-10961:
-------------------------------------
Component/s: (was: Kafka Connector)
Scala API
> RuntimeException: Could not extract key when using closure
> -----------------------------------------------------------
>
> Key: FLINK-10961
> URL: https://issues.apache.org/jira/browse/FLINK-10961
> Project: Flink
> Issue Type: Bug
> Components: Scala API
> Affects Versions: 1.6.2
> Reporter: Avi Levi
> Priority: Major
>
> I am getting this exception when I tried to extract the key using external value e.g
> {code:java}
> val partitionFactor = 10
> val domainsSrc = env
> .addSource(kafkaConsumer)
> .keyBy(_.id.hashCode % partitionFactor
> .map(...)
> {code}
> I am getting this exception
> {code:java}
> java.lang.RuntimeException: Could not extract key from Foo("some-uuid","text",1540348398,1)
> ....
> Caused by: java.lang.ArithmeticException: / by zero
> {code}
> however when I simply use it like
> {code:java}
> val domainsSrc = env
> .addSource(kafkaConsumer)
> .keyBy(_.id.hashCode % 10
> .map(...)
> {code}
> it works fine
