[jira] [Created] (FLINK-4196) Remove "recoveryTimestamp"

Stephan Ewen created FLINK-4196:
-----------------------------------

             Summary: Remove "recoveryTimestamp"
                 Key: FLINK-4196
                 URL: https://issues.apache.org/jira/browse/FLINK-4196
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing
    Affects Versions: 1.0.3
            Reporter: Stephan Ewen


I think we should remove the {{recoveryTimestamp}} that is attached on state restore calls.

Given that this is a wall clock timestamp from a master node, which may change when clocks are adjusted, and between different master nodes during leader change, this is an unsafe concept.
