Use one's own ES instance

[xinyuluo]

Hi! I'm quite new with Elasticsearch, so please let me know if my question needs some clarifications.

I understand that when you run java -jar photon-0.3.5.jar, it starts an internal elasticsearch node and gets elasticsearch clients. I wonder if it's possible to use my own elasticsearch instance? I tried (but failed):

$ sudo -u elasticsearch java -jar photon-0.3.5.jar

I wonder if this is some issue with my config. I tried to look for ES config that Photon uses but failed to find one. Could someone please direct me to it? Thank you.

You need to use the -transport-addresses parameter which takes a comma-separated list of external ES instances. The external server must be at version 5.6. Newer versions won't work.

Thank you @lonvia ! It works. May I ask if there's an ES config that Photon uses? I don't see an elasticsearch.yml file, but does it exist in some other forms? Thank you.

There is no explicit configuration for ES running in embedded mode.

How should I start elastic? I get errors on startup
