------------------------------------
Summary: Changelog cannot close stream normally while enabling
compression
Key: FLINK-28602
URL: https://issues.apache.org/jira/browse/FLINK-28602
Project: Flink
Issue Type: Bug
Components: Runtime / State Backends
Affects Versions: 1.15.1, 1.16.0
Reporter: Hangxiang Yu
Fix For: 1.16.0, 1.15.2
While enabling compression, Changelog part will wrap output stream using
StreamCompressionDecorator#decorateWithCompression.
As the comment said, "IMPORTANT: For streams returned by this method, \{@link
OutputStream#close()} is not propagated to the inner stream. The inner stream
must be closed separately.".
But StateChangeFsUploader will not close inner stream if wrapped stream has
been closed.
So the upload will not complete when enabling compression even if it returns
success.
