Daniel Warneke commented on FLINK-939:
--------------------------------------
I pushed the code to my private git repository for further discussion:
https://github.com/warneke/incubator-flink
The new BLOB service is fully implemented, documented, and integrated. However,
I still need to write unit tests. Moreover, I have not been able to test the
new service in a distributed environment.
Comments are welcome.

> 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.
