Enable Audit Collection Enable collection of audit events from the service's roles. false navigator_audit_enabled false
Audit Event Filter Event filters are defined in a JSON object like the following: { "defaultAction" : ("accept", "discard"), "rules" : [ { "action" : ("accept", "discard"), "fields" : [ { "name" : "fieldName", "match" : "regex" } ] } ] } A filter has a default action and a list of rules, in order of precedence. Each rule defines an action, and a list of fields to match against the audit event. A rule is "accepted" if all the listed field entries match the audit event. At that point, the action declared by the rule is taken. If no rules match the event, the default action is taken. Actions default to "accept" if not defined in the JSON object. The following is the list of fields that can be filtered for Solr events:
  • operation: the Solr operation being performed.
  • username: the user performing the action.
  • ipAddress: the IP from where the request originated.
  • allowed: whether the operation was allowed or denied.
 navigator.event.filter navigator_audit_event_filter false
Audit Queue Policy Action to take when the audit event queue is full. Drop the event or shutdown the affected process. navigator.batch.queue_policy DROP navigator_audit_queue_policy false
Audit Event Tracker Configures the rules for event tracking and coalescing. This feature is used to define equivalency between different audit events. When events match, according to a set of configurable parameters, only one entry in the audit list is generated for all the matching events. Tracking works by keeping a reference to events when they first appear, and comparing other incoming events against the "tracked" events according to the rules defined here. Event trackers are defined in a JSON object like the following: { "timeToLive" : [integer], "fields" : [ { "type" : [string], "name" : [string] } ] } Where:
  • timeToLive: maximum amount of time an event will be tracked, in milliseconds. Must be provided. This defines how long, since it's first seen, an event will be tracked. A value of 0 disables tracking.
  • fields: list of fields to compare when matching events against tracked events.
Each field has an evaluator type associated with it. The evaluator defines how the field data is to be compared. The following evaluators are available:
  • value: uses the field value for comparison.
  • userName: treats the field value as a userName, and ignores any host-specific data. This is useful for environment using Kerberos, so that only the principal name and realm are compared.
The following is the list of fields that can be used to compare Solr events:
  • operation: the Solr operation being performed.
  • username: the user performing the action.
  • ipAddress: the IP from where the request originated.
  • allowed: whether the operation was allowed or denied.

Service Triggers The configured triggers for this service. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific service.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the followig JSON formatted trigger fires if there are more than 10 DataNodes with more than 500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleType = DataNode and last(fd_open) > 500) DO health:bad", "streamThreshold": 10, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Sentry Global Policy File HDFS path to the global policy file for Sentry authorization. This should be a relative path (and not a full HDFS URL). The global policy file must be in Sentry policy file format. sentry.solr.provider.resource /user/solr/sentry/sentry-provider.ini sentry_solr_provider_resource false
Enable Sentry Authorization using Policy Files Use Sentry to enable role-based, fine-grained authorization. This configuration enables Sentry using policy files. To enable Sentry using Sentry service instead (supported in CDH 5.8 and later), add Sentry service as a dependency to Solr service. Sentry service provides concurrent and secure access to authorization policy metadata and is recommended for enabling Sentry. Sentry with policy files is supported only on CDH 5 or later deployments. Sentry requires authentication to be turned on for Solr. false solr_sentry_enabled false
Sentry User to Group Mapping Class The class to use in Sentry authorization for user to group mapping. Sentry authorization may be configured to use either Hadoop groups or local groups defined in the policy file. When configured with Hadoop groups, Sentry will ask the HDFS Namenode for group mapping for a given user to determine authorization access. sentry.provider org.apache.sentry.provider.file.HadoopGroupResourceAuthorizationProvider solr_sentry_provider false

Security

Kerberos Principal Kerberos principal short name used by all roles of this service. solr kerberos_princ_name true
Active Directory Domain This parameter is useful when authenticating against an Active Directory server. This value is appended to all usernames before authenticating against AD. For example, if this parameter is set to "my.domain.com", and the user authenticating is "mike", then "mike@my.domain.com" is passed to AD. If this field is unset, the username remains unaltered before being passed to AD. ldap_domain false
Enable LDAP Authentication When checked, LDAP-based authentication for users is enabled. false solr_enable_ldap_auth false
Solr TLS/SSL Server JKS Keystore File Location The path to the TLS/SSL keystore file containing the server certificate and private key used for TLS/SSL. Used when Solr is acting as a TLS/SSL server. The keystore must be in JKS format. solr_https_keystore_file false
Solr TLS/SSL Server JKS Keystore File Password The password for the Solr JKS keystore file. solr_https_keystore_password false
Solr TLS/SSL Certificate Trust Store File The location on disk of the trust store, in .jks format, used to confirm the authenticity of TLS/SSL servers that Solr might connect to. This is used when Solr is the client in a TLS/SSL connection. This trust store must contain the certificate(s) used to sign the service(s) connected to. If this parameter is not provided, the default list of well-known certificate authorities is used instead. solr_https_truststore_file false
Solr TLS/SSL Certificate Trust Store Password The password for the Solr TLS/SSL Certificate Trust Store File. This password is not required to access the trust store; this field can be left blank. This password provides optional integrity checking of the file. The contents of trust stores are certificates, and certificates are public information. solr_https_truststore_password false
LDAP BaseDN This parameter is useful when authenticating against a non-Active Directory server, such as OpenLDAP. When set, this parameter is used to convert the username into the LDAP Distinguished Name (DN), so that the resulting DN looks like uid=username,this parameter. For example, if this parameter is set to "ou=People,dc=cloudera,dc=com", and the username passed in is "mike", the resulting authentication passed to the LDAP server look like "uid=mike,ou=People,dc=cloudera,dc=com". This parameter is mutually exclusive with Active Directory Domain. solr_ldap_basedn false
Enable LDAP TLS If true, attempts to establish a TLS (Transport Layer Security) connection with an LDAP server that was specified with ldap://. Not required when using an LDAP URL with prefix ldaps://, because that already specifies TLS. This option is also known as "Use StartTLS". false solr_ldap_enable_starttls false
LDAP URL The URL of the LDAP server. The URL must be prefixed with ldap:// or ldaps://. The URL can optionally specify a custom port, for example: ldaps://ldap_server.example.com:1636. Note that usernames and passwords will be transmitted in the clear unless either an ldaps:// URL is used, or "Enable LDAP TLS" is turned on (where available). Also note that encryption must be in use between the client and this service for the same reason.For more detail on the LDAP URL format, see RFC 2255 . A space-separated list of URLs can be entered; in this case the URLs will each be tried in turn until one replies. solr_ldap_uri false
Solr Secure Authentication Choose the authentication mechanism used by Solr. simple solr_security_authentication false
Enable TLS/SSL for Solr Encrypt communication between clients and Solr using Transport Layer Security (TLS) (formerly known as Secure Socket Layer (SSL)). Additional manual steps must be performed; see Enabling TLS/SSL for Solr. false solr_use_ssl false
