I believe this assert message should read "Response should have one error
and zero successes"
> Error Handling in ElasticsearchWriter
> -------------------------------------
>
> Key: METRON-326
> URL: https://issues.apache.org/jira/browse/METRON-326
> Project: Metron
> Issue Type: Bug
> Reporter: Ajay Yadav
> Assignee: Justin Leet
>
> In Elasticsearch writer we raise a exception if BulkResponse object has
> failures and that results in failing the whole batch even if some objects
> failed in it. This has spiral effect specially when there is continuous
> stream of bad messages and errorStream is tied to indexingBolt.
> If possible we should iterate through items in BulkResponse object and send
> only failed messages to errorStream.
