Folks - Thank you so much for helping newbie like me on ELK. Currently I am evaluating ELK and soon may be going production with it. Have some basic question.

1.) Data ingestion: After initial ingestion of a CSV file to a index in ES, if I have another CSV file with the new data in them, can I ingest new data to the same index in ES. These are all same data data generated on different day.

2.) Currently I m evaluating ELK, so I am running as a user account on a linux machine with ES and Kibana running on the same machine but when we move to production, I would like this to run as a service and not tied to a user account. how can I do that ?

3.) Going forward I may need to add bunch of ES machines, can it be done easily

4.) I noticed that it can also use hadoop for distributed storage (HDFS). Is it a good thing to do to leverage your exising hadoop architrecture

5.) How do use data protection ( authentication/authorization)

Read: [Elastic Stack: Elasticsearch, Kibana, Beats & Logstash | Elastic](https://www.elastic.co/elk-stack) 😉

> can I ingest new data to the same index in ES?

Yes. As long as you don't use the same `_id` or let elasticsearch autogenerate it, you can always append new data.

> I would like this to run as a service and not tied to a user account. how can I do that ?

Have a look at

- [Installing Elasticsearch | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html)
- [Install Kibana | Kibana Guide [8.11] | Elastic](https://www.elastic.co/guide/en/kibana/current/install.html)

And choose the right package for your OS and you should be ok.

> Going forward I may need to add bunch of ES machines, can it be done easily

Look at [Important Elasticsearch configuration | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/important-settings.html#unicast.hosts)

But in short: yes

> I noticed that it can also use hadoop for distributed storage (HDFS). Is it a good thing to do to leverage your exising hadoop architrecture

So not exactly. You can use HDFS to do snapshot and restore. But don't store your indices on HDFS.

> How do use data protection ( authentication/authorization)

X-pack (commercial plugin) provides that.
