Thank you Gordon and Ken. My Flink job is now running well with 1.7.2 RC1, with failed ES request retried successfully.
One more question I have on this is how to limit the number of retries for different types of errors with ES bulk request. Is there any guideline on that? My temporary solution is to use the version field of each ER request - increase it for every time I retried putting the request into the queue. This works for me until now, but it doesn't look right.
