Observed: Liferay starts Sidecar Elasticsearch, connects, Search works.
Go to "Elasticsearch configuration". (LPS-105070)
Enable checkbox: "Connect to a Remote Elasticsearch Server"
Observed: Liferay shuts down Sidecar Elasticsearch, attempts to connect to localhost 9200, fails.
Start Elasticsearch manually from the command line.
Observed: Liferay connects to localhost 9200, Search works.
Default port of Remote must be 9200, default port of Sidecar must be anything other than 9200. This allows starting a Remote Elasticsearch Server on 9200 before Portal starts Sidecar elsewhere, no conflicts. (
