Chris Sampson commented on NIFI-1576:
-------------------------------------
Fetch/PutElasticsearch processors have been removed from nifi
The newer Elasticsearch REST API based processors cover all the functionality
(and more) or these original processors and have taken the suggestions within
this ticket into account where applicable
> Incorporate feedback/improvements to Elasticsearch processors
> -------------------------------------------------------------
>
> Key: NIFI-1576
> URL: https://issues.apache.org/jira/browse/NIFI-1576
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Matt Burgess
> Priority: Major
>
> Since the release of Apache NiFi 0.5.0 containing FetchElasticsearch and
> PutElasticsearch processors, there have been some improvements identified
> that would add to the usability, flexibility, and power of the Elasticsearch
> processor(s). This Jira should capture those improvements for incorporation
> in a future release.
> Three initial observations:
> 1) FetchElasticsearch currently requires input, but it is possible to
> configure the processor such that no information is required from an incoming
> flow file. The processor should be changed to allow (but not require) input.
> 2) FetchElasticsearch specifies a "Document Identifier" property which may or
> may not contain Expression Language to determine the document ID for
> fetching. However PutElasticsearch only works when the IDs are unique, so it
> specifies a "Identifier Attribute" which forces the user to point at an
> existing attribute. The documentation should be very clear about what the
> properties are and why/how they're used.
> 3) Related to #2, PutElasticsearch's "Identifier Attribute" is required and a
> value for that attribute is currently required. Instead, if no value is
> present, the processor should leverage the auto-generated ID feature of the
> Elasticsearch API.
