-------------------------------------
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.
