--------------------------------
Issue Type: Bug (was: Improvement)
> JdbcBatchingOutputFormat should not generate circulate chaining of exceptions
> when flushing fails in timer thread
> -----------------------------------------------------------------------------------------------------------------
>
> Key: FLINK-24677
> URL: https://issues.apache.org/jira/browse/FLINK-24677
> Project: Flink
> Issue Type: Bug
> Components: Connectors / JDBC
> Affects Versions: 1.15.0
> Reporter: Caizhi Weng
> Priority: Major
>
> This is reported from the [user mailing
> list|https://lists.apache.org/thread.html/r3e725f52e4f325b9dcb790635cc642bd6018c4bca39f86c71b8a60f4%40%3Cuser.flink.apache.org%3E].
> In the timer thread created in {{JdbcBatchingOutputFormat#open}},
> {{flushException}} field will be recorded if the call to {{flush}} throws an
> exception. This exception is used to fail the job in the main thread.
> However {{JdbcBatchingOutputFormat#flush}} will also check for this exception
> and will wrap it with a new layer of runtime exception. This will cause a
> super long stack when the main thread finally discover the exception and
> fails.
