Apache MiNifi- Putelasticsearch

Question

i make flow, which process real time data from local server and send relevant data to Elasticsearch. I use Minifi, but when I run MiNifi it returned the following error. Does anyone know, where is the issue?

Thanks

In order to reduce its footprint, MiNiFi java only ships with the standard bundle of processors. In order to use the other processors that are present within a standard NiFi deployment in MiNiFi, you need to put the appropriate "nar" file into the "lib" of the MiNiFi deployment.

For "PutElasticSearch" you need "nifi-elasticsearch-nar-.nar" where "" is the version of NiFi that your version of MiNiFi is built off of. Versions 0.4.0 of MiNiFi java uses NiFi 1.5.0.

For more information and a list of the processors that do come bundled with MiNiFi out of the box see the "MiNiFi Java Agent Quick Start" documentation, section "Using Processors Not Packaged with MiNiFi"[1]. For more information on the different versions of MiNiFi correspond to the version of NiFi frameworks, see here[2].
