> Provide Flink binary release without Hadoop
> -------------------------------------------
>
> Key: FLINK-2268
> URL: https://issues.apache.org/jira/browse/FLINK-2268
> Project: Flink
> Issue Type: Improvement
> Components: Build System
> Reporter: Robert Metzger
> Assignee: Aljoscha Krettek
>
> Currently, all Flink releases ship with Hadoop 2.3.0 binaries.
> The big Hadoop distributions are usually not relying on vanilla Hadoop
> releases, but on custom patched versions.
> To provide the best user experience, we should offer a Flink binary that uses
> the Hadoop jars provided by the user (=hadoop distribution)
