[jira] [Created] (FLINK-5290) Ensure backwards compatibility of the
hashes used to generate JobVertexIds
Stefan Richter created FLINK-5290:
-------------------------------------
Summary: Ensure backwards compatibility of the hashes used to generate JobVertexIds
Key: FLINK-5290
URL: https://issues.apache.org/jira/browse/FLINK-5290
Project: Flink
Issue Type: Sub-task
Reporter: Stefan Richter
Assignee: Stefan Richter
The way in which hashes for JobVertexIds are generated changed between Flink 1.1 and 1.2 (parallelism was considered for the hash in 1.1). We need to be backwards compatible to old JobVertexId generation so that we can still assign state from old savepoints.
