Description

JdbcBatchingOutputFormat contains a retry mechanism on potential SQLException (usually because of lost connection).

The retry works perfectly but the exception stack trace (usually useless) is logged at ERROR level on every retry.

I am proposing to just log the retry attempt as a warning
