ASF GitHub Bot commented on FLINK-4316: --------------------------------------- Github user StephanEwen commented on the issue: https://github.com/apache/flink/pull/2338 The Scala type extraction has now also been addressed. > Make flink-core independent of Hadoop > ------------------------------------- > > Key: FLINK-4316 > URL: https://issues.apache.org/jira/browse/FLINK-4316 > Project: Flink > Issue Type: Bug > Components: Core > Affects Versions: 1.1.0 > Reporter: Stephan Ewen > Assignee: Stephan Ewen > Fix For: 1.2.0 > > > We want to gradually reduce the hard and heavy mandatory dependencies in > Hadoop. Hadoop will still be part of (most) flink downloads, but the API > projects should not have a hard dependency on Hadoop. > I suggest to start with {{flink-core}}, because it only depends on Hadoop for > the {{Writable}} type, to support seamless operation of Hadoop types. > I propose to move all {{WritableTypeInfo}}-related classes to the > {{flink-hadoop-compatibility}} project and access them via reflection in the > {{TypeExtractor}}. > That way, {{Writable}} types will be out of the box supported if users have > the {{flink-hadoop-compatibility}} project in the classpath. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
