He has also implemented tests for them https://github.com/GJL/flink/blob/FLINK-12433/flink-runtime/src/test/java/org/apache/flink/runtime/scheduler/ExecutionVertexVersionerTest.java. I've ported these tests and made some minor changes. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
