Jiayi Liao created FLINK-16597:
----------------------------------
Summary: tryCleanupOnError should happen before close
Key: FLINK-16597
URL: https://issues.apache.org/jira/browse/FLINK-16597
Project: Flink
Issue Type: Improvement
Components: Runtime / Task
Affects Versions: 1.10.0
Reporter: Jiayi Liao
If {{DataSinkTask}} fails or throws an exception, the {{OutputFormat}} will
call {{tryCleanupOnError}} before {{close}}. But the calling order is reverse
when {{DataSinkTask}} is cancelled, which doesn't make much sense that we can
still clean the output format after it's closed.
I'm not very sure if this is a bug. But this does mislead our developers when
implementing the {{OutputFormat}}.
