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 .
