Configuring Spark2x Web UI ACLs

Scenario

Users need to implement security protection for Spark2x web UI when some data on the UI cannot be viewed by other users. Once a user attempts to log in to the UI, Spark2x can check the view ACL of the user to determine whether to allow the user to access the UI.

Spark2x has two types of web UI. One is for running tasks. You can access the web UI using the application link on the native Yarn page or the REST APIs. The other one is for ended tasks. You can access the web UI using the Spark2x JobHistory service or the REST APIs.

This section applies only to clusters in security mode (with Kerberos authentication enabled).

  • Configuring the ACL of the web UI for running tasks

    For a running task, you can set the following parameters on the server:

    • spark.admin.acls: specifies the web UI administrator list.
    • spark.admin.acls.groups: specifies the administrator group list.
    • spark.ui.view.acls: specifies the Yarn page visitor list.
    • spark.modify.acls.groups: specifies the Yarn page visitor group list.
    • spark.modify.acls: specifies the web UI modifier list.
    • spark.ui.view.acls.groups: specifies the web UI modifier group list.
  • Configuring the ACL of the web UI for ended tasks

    For ended tasks, use client parameter spark.history.ui.acls.enable to enable or disable the ACL access permission.

    If ACL control is enabled, configure client parameters spark.admin.acls and spark.admin.acls.groups to specify the web UI administrator list and administrator group list. Use client parameters spark.ui.view.acls and spark.modify.acls.groups to specify the visitor list and visitor group list that view web UI task details. Use client parameters spark.modify.acls and spark.ui.view.acls.groups to specify the visitor list and group list that modify web UI task details.

Configuration

Log in to FusionInsight Manager, choose Cluster > Name of the desired cluster > Services > Spark2x > Configurations, click All Configurations, search for acl, and modify the following parameters on the JobHistory, JDBCServer, SparkResource, and Spark pages.

Table 1 Parameter description

Parameter

Description

Default Value

spark.history.ui.acls.enable

Indicates whether JobHistory supports the permission verification of a single task.

true

spark.acls.enable

Indicates whether to enable Spark permission management.

If this function is enabled, the system checks whether the user has the permission to access and modify task information.

true

spark.admin.acls

Indicates the list of Spark administrators. All members in the list have the rights to manage all Spark tasks. You can configure multiple administrators and separate them from each other using commas (,).

admin

spark.admin.acls.groups

Indicates the list of Spark administrator groups. All groups in the list have the permission to manage all Spark tasks. You can configure multiple administrator groups and separate them from each other using commas (,).

-

spark.modify.acls

Indicates the list of members that have the permission to modify Spark tasks. By default, the user who starts a task has the permission to modify the task. You can configure multiple users and separate them from each other using commas (,).

-

spark.modify.acls.groups

Indicates the list of groups that have the permission to modify Spark tasks. You can configure multiple groups and separate them from each other using commas (,).

-

spark.ui.view.acls

Indicates the list of members that have the permission to access Spark tasks. By default, the user who starts a task has the permission to modify the task. You can configure multiple users and separate them from each other using commas (,).

-

spark.ui.view.acls.groups

Indicates the list of groups that have the permission to access Spark tasks. You can configure multiple groups and separate them from each other using commas (,).

-

If you use a client to submit tasks, you must download the client again after modifying the spark.admin.acls, spark.admin.acls.groups, spark.modify.acls, spark.modify.acls.groups, spark.ui.view.acls, and spark.ui.view.acls.groups parameters.
