> HybridShuffle: RemoteTier should not finish empty segments

> Key: FLINK-37801
> URL: https://issues.apache.org/jira/browse/FLINK-37801
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Task
> Reporter: David Morávek
> Assignee: David Morávek
> Priority: Major
>
> When there are not segments opened for a given sub-partition of the
> RemoteTier, we still write out FINISH marker for EMPTY_SEGMENT_ID (segmentId
> = -1). This causes unnecessary on the remote storage and is quite costly.
