Properties:

In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values, whether a property supports the NiFi Expression Language, and whether a property is considered “sensitive”, meaning that its value will be encrypted. Before entering a value in a sensitive property, ensure that the nifi.properties file has an entry for the property nifi.sensitive.props.key.

Name	Default Value	Allowable Values	Description
Cluster Name	elasticsearch		Name of the ES cluster (for example, elasticsearch_brew). Defaults to 'elasticsearch' Supports Expression Language: true
ElasticSearch Hosts			ElasticSearch Hosts, which should be comma separated and colon for hostname/port host1:port,host2:port,.... For example, testcluster:9300. This processor uses the Transport Client to connect to hosts. The default transport client port is 9300. Supports Expression Language: true
SSL Context Service		Controller Service API: SSLContextService Implementations: StandardSSLContextService StandardRestrictedSSLContextService	The SSL Context Service used to provide client certificate information for TLS/SSL connections. This service only applies if the Elasticsearch endpoint(s) have been secured with TLS/SSL.
X-Pack Transport Location			Specifies the path to the JAR(s) for the Elasticsearch X-Pack Transport feature. If the Elasticsearch cluster has been secured with the X-Pack plugin, then the X-Pack Transport JARs must also be available to this processor. Note: Do NOT place the X-Pack JARs into NiFi's lib/ directory, doing so will prevent the X-Pack Transport JARs from being loaded. Supports Expression Language: true
Username			Username to access the Elasticsearch cluster Supports Expression Language: true
Password			Password to access the Elasticsearch cluster Sensitive Property: true
ElasticSearch Ping Timeout	5s		The ping timeout used to determine when a node is unreachable. For example, 5s (5 seconds). If non-local recommended is 30s Supports Expression Language: true
