-----------------------------------

             Summary: 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: Improvement
          Components: Connectors / JDBC
    Affects Versions: 1.15.0
            Reporter: Caizhi Weng


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.
