----------------------------------
Summary: Support Elasticsearch 5.0 for Put/FetchElasticsearch
processors
Key: NIFI-3011
URL: https://issues.apache.org/jira/browse/NIFI-3011
Project: Apache NiFi
Issue Type: New Feature
Components: Extensions
Reporter: Matt Burgess
Now that Elastic has released a new major version (5.0) of Elasticsearch, the
Put/FetchElasticsearch processors would need to be upgraded (or duplicated) as
the major version of the transport client needs to match the major version of
the Elasticsearch cluster.
If upgrade is selected, then Put/FetchES will no longer work with Elasticsearch
2.x clusters, so in that case users would want to switch to the Http versions
of those processors. However this might not be desirable (due to performance
concerns with the HTTP API vs the transport API), so care must be taken when
deciding whether to upgrade the existing processors or create new ones.
Creating new versions of these processors (to use the 5.0 transport client)
will also take some consideration, as it is unlikely the different versions can
coexist in the same NAR due to classloading issues (multiple versions of JARs
containing the same class names, e.g.). It may be necessary to create an
"elasticsearch-5.0" version of the NAR, containing only the new versions of
these processors.
