xiangyu feng updated FLINK-33684:
---------------------------------
    Description: 
Currently  CollectResultFetcher use a fixed retry interval.
{code:java}
private void sleepBeforeRetry() {
    if (retryMillis <= 0) {
        return;
    }

    try {
        // TODO a more proper retry strategy?
        Thread.sleep(retryMillis);
    } catch (InterruptedException e) {
        LOG.warn("Interrupted when sleeping before a retry", e);
    }
} {code}
This can be improved with a RetryStrategy.
