-----------------------------------
Status: Patch Available (was: Open)
> Remove Elasticsearch 5 Processors
> ---------------------------------
>
> Key: NIFI-9541
> URL: https://issues.apache.org/jira/browse/NIFI-9541
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: David Handermann
> Assignee: David Handermann
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Elasticsearch 5.0 reached end of life on 2018-04-26, and Elasticsearch 5.6
> reached end of life on 2019-03-11 according to [Elasticsearch support
> documentation|https://www.elastic.co/support/eol].
> The NiFi Elasticsearch 5 processors leverage client version 5.0.1 which
> provides narrow compatibility with different Elasticsearch 5 versions using
> the deprecated transport protocol. The NiFi Elasticsearch 5 processors are
> not built as part of the convenience binary release, but can be downloaded
> separately from Maven Central Repository.
> With Elasticsearch 5 no longer received updates, and alternative
> Elasticsearch components available in NiFi using the supported REST protocol,
> maintaining the current Elasticsearch 5 components will become more difficult
> down the road. With the ability to run NAR files from previous versions,
> users requiring Elasticsearch 5 components can continue to download the
> Elasticsearch 5 NAR files from Maven Central.
