Elastic Stack Elasticsearch

Hi,

we are using Elasticsearch 7.6.1 and CDH 6.2. we need to get data from elasticsearch to hive in CSV format but we dont know the way.
any document which i go through have steps for loading data from hive to elaticsearch.
as the data is on production we cant install any new tool. only tool we have is nifi but i dont know the exact configuration its required. we dont have any security restriction nor i have setup password for Elasticsearch.

please let me know how to load data from elasticsearch to hive on current date basis in csv format. its urgent i will really appreciate the effort.

thanks
