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)
