Stephan Ewen commented on FLINK-939:
------------------------------------
I am merging this with the latest version (the renamed one). In order to
minimize the number of times we need to resolve merge conflicts, I squashed all
commits into one.
> Distribute required JAR files with seperate service

> 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.
