This does leave things in an inconsistent state and will makes things
confusing for anyone working with these classes. However I think a follow up
PR would be fine.
Are you aware of the
[ConfigOption](https://github.com/apache/metron/blob/master/metron-platform/metron-common/src/main/java/org/apache/metron/common/configuration/ConfigOption.java)
interface? It looks like there may be some duplication with this class.
> Allow Customization of Elasticsearch Document ID
> ------------------------------------------------
>
> Key: METRON-1801
> URL: https://issues.apache.org/jira/browse/METRON-1801
> Project: Metron
> Issue Type: Sub-task
> Reporter: Nick Allen
> Assignee: Nick Allen
> Priority: Major
>
> The user should be able to customize the document ID that is set by the
> client when indexing documents into Elasticsearch. The user should be able
> to use the Metron GUID, define their own custom document ID, or choose to not
> have the document ID set by the client.
>
> This task covers Elasticsearch only. An additional task should be created to
> cover Solr.
