Connect to Elasticsearch

When establishing a connection to an Elasticsearch data store, make sure you:

1. Specify the connection string in the following format:

   Protocol	Connection String Format	Example
   HTTP/HTTPS	<schema>://<host1>:<port1>,...,<hostN>:<postN>/<prefix>	http://ip-10-2-2-241.ec2.internal:80/es
   Transport/Transports	<schema>://<host1>:<port1>,...,<hostN>:<portN>	transports://10.2.2.2:9010,10.2.2.3:9010

   where <schema> is the protocol that you want to use:

• http or https (with SSL support)

• transport or transports (with SSL support)

Bear in mind that you must specify the hosts within one cluster.

Important: Elasticsearch 8 does not support transports. Use an http:// or https:// connection when connecting to or upgrading to Elasticsearch 8 by updating your connection string as needed, for example, replace transport://1.1.1.1:9300,2.2.2.2:9300 with https://localhost:9200.


2. Specify your Elasticsearch cluster name.

3. If required, specify your Elasticsearch User Name and Password.

4. Select Validate to confirm your connection.

To connect to your Elasticsearch cluster and data set secured by X-Pack, see Support of X-Pack for Elasticsearch.

Connect to Elasticsearch with a Configured Custom Certificate

If your Elasticsearch cluster is configured with a custom certificate, you should configure a truststore for the Elasticsearch connector.

Connect to an Elasticsearch data store with a configured custom certificate

1. Copy a truststore to the machine on which the Elasticsearch connector is running.

2. Add the following lines to file the appropriate Elasticsearch jvm file.

   • For Linux: , /etc/zoomdata/edc-elasticsearch-7.0.jvm, or /etc/zoomdata/edc-elasticsearch-8.0.jvm. Copy these files from the /opt/zoomdata/conf directory if a copy is not in /etc/zoomdata/.

   • For Windows: , <install-path>/edc-elasticsearch-7.0.jvm or <install-path>/edc-elasticsearch-8.0.jvm. Copy these files from the <install-path>/conf directory if a copy is not in <install-path>.

   -Djavax.net.ssl.trustStore=<path_to_truststore>
   -Djavax.net.ssl.trustStorePassword=<truststore_password>

   Replace:

   • <path_to_truststore> with an absolute path to your truststore

   • <truststore_password> with a password for your truststore
