> Add Hadoop to the parent-first loading patterns
> -----------------------------------------------
>
> Key: FLINK-8455
> URL: https://issues.apache.org/jira/browse/FLINK-8455
> Project: Flink
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.4.0
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Priority: Blocker
> Fix For: 1.5.0, 1.4.1
>
>
> Various users have reported issues (mainly in the BucketingSink) where they
> get ClassCastExceptions related to Hadoop classes.
> In all cases, users had Hadoop dependencies bundled into their application
> jar files. To make the experience better, I suggest to let Hadoop always load
> its classes parent-first.
