Subject [GitHub] flink issue #2861: [FLINK-5122] Index requests will be retried if the error ...

Github user tzulitai commented on the issue:

    https://github.com/apache/flink/pull/2861
  
    Small note (would be great if @static-max can clarify this also) on matching the exceptions:
    We can actually use `BulkItemResponse.getFailure().getCause()` to get a `Throwable` that
we can use to match the exceptions, instead of unstable String matching.
    
    After surfing the Javadocs a bit, I think the below exceptions refer to what you were
trying to catch before:
    - `EsRejectedExecutionException`: the queue on ES node is temporarily full
    - `ElasticsearchTimeoutException`: timeout from Elasticsearch
    - `ClusterBlockException`: no master
    - `UnavailableShardsException` - currently no shards available
    
    @static-max do you think the above exception types are reasonable to be considered "temporary"
(have you seen them before in logs)? I'm personally a bit unsure of the last two. I don't
have that much experience with operating an Elasticsearch cluster, and their Javadocs really
don't say much, so some input from you will be helpful :)
