Configure the Elasticsearch Properties File

Informatica provides a sample Elasticsearch properties file. To configure Elasticsearch, edit the properties file.

Find the

elasticsearch.yml

file in the following directory:

<elasticsearch installation directory>/config

Use a text editor to open the file, and edit the following properties:

Property	Description
bootstrap.memory_lock	Sets up memory locking. To prevent any Elasticsearch memory from being swapped out, set to true . Default is true .
cluster.name	Specify a unique name for the Elasticsearch cluster. If you have multiple clusters, ensure that the name of each cluster is unique. If a cluster has multiple nodes, ensure that on each node of the cluster, the same cluster name is specified.
discovery.zen.minimum_master_nodes	Required for a multi-node cluster to prevent data loss and maintain cluster stability. Set to the following value: (number of master-eligible nodes / 2) + 1 For example, if a cluster has three nodes, all of which are master-eligible nodes and can contain data, then set the property to (3 / 2) + 1 , which is rounded to 2 .
discovery.zen.ping.unicast.hosts	Required for a multi-node cluster. This property is used to specify the discovery setting, which is a list of IP addresses and transport ports of the nodes in the cluster. Use the following format to set the property: ["host1:port1","host2:port2","host3:port3"]
http.port	Port for the HTTP requests. Default is 9200 .
network.host	The IP address of the host to use as the bind address.
node.data	Enables a node as a data node that performs data related operations, such as CRUD and search. Default is true .
node.ingest	Enables a node as an ingest node that transforms and enriches the data before indexing. Default is true .
node.master	Enables a node as a master node that controls the cluster. If a cluster has multiple nodes, enable at least one of the nodes as a master node. For high availability, set multiple nodes as master nodes. Default is true .
node.name	Specify a unique name for the node.
path.data	Path to the directory where you want to store the data. You can configure multiple data directories. For more information about configuring multiple data directories, see the Elasticsearch documentation.
path.logs	Path to the log files.
transport.tcp.port	The TCP bind port. Default is 9300 .
searchguard.enterprise_modules_enabled	Specifies whether you want to enable Search Guard Enterprise Edition. To avoid license violation, always set the property to false . The MDM Hub installer includes Search Guard Community Edition, which is free. Informatica does not include a license for Search Guard Enterprise Edition.
searchguard.ssl.transport.keystore_type	The type of keystore file. Set to JKS . Default is JKS .
searchguard.ssl.transport.keystore_filepath	Relative path to the keystore file. If you used the sip_ant script to create the keystore, use the default path. Default is MDM_ESKEYSTORE_FILE_JKS.keystore .
searchguard.ssl.transport.keystore_password	The keystore password. Default is infa@1234 .
searchguard.ssl.transport.truststore_type	The type of truststore file. Set to JKS . Default is JKS .
searchguard.ssl.transport.truststore_filepath	Relative path to the truststore file. If you used the sip_ant script to create the truststore, use the default path. Default is MDM_ESTRUSTSTORE_FILE_JKS.keystore .
searchguard.ssl.transport.truststore_password	The truststore password. Default is infa@1234 .
searchguard.ssl.http.enabled	Specifies whether you want to enable transport layer security (TLS) on the REST layer. Set to true . Default is true .
searchguard.ssl.http.clientauth_mode	Specifies whether you want to use the TLS client authentication mode on the REST layer. Set to REQUIRE . Default is REQUIRE .
searchguard.ssl.http.keystore_type	The type of keystore file. Set to JKS . Default is JKS .
searchguard.ssl.http.keystore_filepath	Relative path to the keystore file. If you used the sip_ant script to create the keystore, use the default path. Default is MDM_ESCLIENT_FILE_JKS.keystore .
searchguard.ssl.http.keystore_password	The keystore password. Default is infa@1234 .
searchguard.ssl.http.truststore_type	The type of truststore file. Set to JKS . Default is JKS .
searchguard.ssl.http.truststore_filepath	Relative path to the truststore file. If you used the sip_ant script to create the truststore, use the default path. Default is MDM_ESTRUSTSTORE_FILE_JKS.keystore .
searchguard.ssl.http.truststore_password	The truststore password. Default is infa@1234 .
searchguard.cert.oid	The object identifier (OID) of the client certificate. Default is 1.2.3.4.5.5 . If you used the sip_ant script to create the certificates, use the default OID. If you did not use the sip_ant script to create the security certificates, you might need to set this property.
searchguard.ssl.transport.enforce_hostname_verification	Specifies whether you want to verify host names on the transport layer. If the certificates are not created by using the sip_ant script, set to true . Default is false .
searchguard.nodes_dn	The DNs of the node certificates to identify requests between the nodes in the Elasticsearch cluster. If you used the sip_ant script to create the certificates, use the default value. Default is - CN=EsNode .
searchguard.authcz.admin_dn	The DN of the client certificate that is also an administrative certificate. If you used the sip_ant script to create the certificates, use the default value. Default is - CN=EsClient .
