[jira] [Created] (FLINK-20063) File Source requests an additional split on every restore.

Stephan Ewen created FLINK-20063:
------------------------------------

             Summary: File Source requests an additional split on every restore.
                 Key: FLINK-20063
                 URL: https://issues.apache.org/jira/browse/FLINK-20063
             Project: Flink
          Issue Type: Bug
          Components: Connectors / FileSystem
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.12.0


Currently, the {{FileSourceReader}} requests a new split when started. That includes cases when it was restored from a checkpoint.

So with every restore, the reader increases its split backlog size by one, causing problems for balanced split assignments.
