Role Triggers

Description

The configured triggers for this role. 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 role.
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 following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:

[{"triggerName": "sample-trigger",
  "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad",
  "streamThreshold": 0, "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.

Audit Event Filter

Description

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 Impala events:

userName: the user performing the action.
ipAddress: the IP from where the request originated.
operation: the Impala operation being performed.
databaseName: the databaseName for the operation.
tableName: the tableName for the operation.

Audit Event Tracker

Description

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 Impala events:

operation: the Impala 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.
databaseName: the database affected by the operation.
tableName: the table affected by the operation.
objectType: the type of object affected by the operation.
privilege: the privilege associated with the operation.

Service Triggers

Description

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 following 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"}]

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.
