"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

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:

| Proxy User Configuration | Specifies the set of authorized proxy users (users who can impersonate other users during authorization) and whom they are allowed to impersonate. Input is a semicolon-separated list of key=value pairs of authorized proxy users to the user(s) they can impersonate. These users are specified as a comma separated list of short usernames, or '*' to indicate all users. For example: joe=alice,bob;hue=*;admin=*. Only valid when Sentry is enabled. | authorized_proxy_user_config | hue=* | impala_authorized_proxy_user_config | false |
Security
| Display Name | Description | Related Name | Default Value | API Name | Required |
|---|---|---|---|---|---|
| Enable TLS/SSL for Impala | Encrypt communication between clients and Impala using Transport Layer Security (TLS) (formerly known as Secure Socket Layer (SSL)). | client_services_ssl_enabled | false | client_services_ssl_enabled | false |
| Enable LDAP Authentication | When checked, LDAP-based authentication for users is enabled. | enable_ldap_auth | false | enable_ldap_auth | 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". | ldap_tls | false | enable_ldap_tls | 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. | ldap_uri | impala_ldap_uri | false | |
| Kerberos Principal | Kerberos principal short name used by all roles of this service. | impala | kerberos_princ_name | true | |
| Kerberos Re-init Interval | Number of minutes between reestablishing our ticket with the Kerberos server. | kerberos_reinit_interval | 1 hour(s) | kerberos_reinit_interval | 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. | ldap_baseDN | ldap_baseDN | false | |
| LDAP Pattern | When set, this parameter allows arbitrary mapping from usernames into a Distinguished Name (DN). The string specified must have a placeholder named "#UID" inside it, and that #UID is replaced with the username. For example, you could mimic the behavior of LDAP BaseDN by specifying "uid=#UID,ou=People,dc=cloudera,dc=com". When the username of "mike" comes in, it replaces the #UID and the result is "uid=mike,ou=People,dc=cloudera,dc=com". This option should be used when more control over the DN is needed. This parameter is mutually exclusive with LDAP Domain and LDAP BaseDN. | ldap_bind_pattern | ldap_bind_pattern | false | |
| 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 | ldap_domain | false | |
| Impala TLS/SSL CA Certificate | The location on disk of the certificate, in PEM format, used to confirm the authenticity of SSL/TLS servers that the Impala daemons might connect to. Because the Impala daemons connect to each other, this should also include the CA certificate used to sign all the SSL/TLS Certificates. Without this parameter, SSL/TLS between Impala daemons will not be enabled. | ssl_client_ca_certificate | ssl_client_ca_certificate | false | |
| Impala TLS/SSL Server Private Key File (PEM Format) | The path to the TLS/SSL file containing the private key used for TLS/SSL. Used when Impala is acting as a TLS/SSL server. The certificate file must be in PEM format. | ssl_private_key | ssl_private_key | false | |
| Impala TLS/SSL Private Key Password | The password for the private key in the Impala TLS/SSL Server Certificate and Private Key file. If left blank, the private key is not protected by a password. | ssl_private_key_password_cmd | ssl_private_key_password | false | |
| Impala TLS/SSL Server Certificate File (PEM Format) | The path to the TLS/SSL file containing the server certificate key used for TLS/SSL. Used when Impala is acting as a TLS/SSL server. The certificate file must be in PEM format. | ssl_server_certificate | ssl_server_certificate | false |
