[jira] [Created] (FLINK-26957) FileSystemJobResultStore calls flush on an already closed OutputStream

Matthias Pohl created FLINK-26957:
-------------------------------------

             Summary: FileSystemJobResultStore calls flush on an already closed OutputStream 
                 Key: FLINK-26957
                 URL: https://issues.apache.org/jira/browse/FLINK-26957
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.15.0, 1.16.0
            Reporter: Matthias Pohl


We experienced problems with some FileSystems when creating the dirty JRS entries (see initial discussion in FLINK-26555). The {{writeValue}} method closes the {{OutputStream}} by default which causes the subsequent {{flush}} call to fail.

It didn't appear in the unit tests because {{LocalDataOutputStream.flush}} is a no-op operation. We still have to investigate why it didn't appear when doing the tests with the presto and hadoop S3 filesystems.
