- users can now also deploy Flink on YARN for executing a single job.
- The flink-yarn project has been moved out of the flink-addons module
- the MiniYARNCluster is used for testing Flink on YARN
- There is now a (undocumented) Java interface Flink's YARN client, allowing users to manually control the Yarn session.
- ALL ports used by Flink when running on YARN are automatically determined. In the past users reported problems with blocked ports (YARN is telling the client the RPC address of the application master)
- The checks before deployment have been improved to give better error messages if the user is requesting too many resources for a YARN session
