---------------------------------

             Summary: Distribute required JAR files with seperate service
                 Key: FLINK-939
                 URL: https://issues.apache.org/jira/browse/FLINK-939
             Project: Flink
          Issue Type: Improvement
            Reporter: Ufuk Celebi
            Assignee: Daniel Warneke


Currently, required user JAR files are distributed via the RPC service in {{JobGraph.writeRequiredJarFiles(DataOutput, AbstractJobVertex[])}}. The RPC service then tries to allocate a buffer on the client side heap to write the on-disk JAR, which [can lead to problems|https://github.com/apache/incubator-flink/pull/18].

This should be replaced with a seperate service.
