# Spark Job场景的LakeFormation授权 提交Spark Job作业前，需通过委托完成LakeFormation的IAM细粒度授权和SQL资源授权（包括元数据、数据库、表、列和函数），以确保作业在Spark集群后台运行时能够正常访问所需数据。本节介绍Spark Job场景的LakeFormation授权的具体操作。 #### 授权操作 在使用LakeFormation资源需要分别完成LakeFormation API的授权和LakeFormation SQL资源授权。Hive、DataSource和Iceberg格式中各SQL语句的权限请参考[Iceberg]和[Hive和DataSource]。 1. 通过委托，授权使用LakeFormation API。 使用Spark Job执行作业时，需要您先在IAM页面创建相关委托，并在配置作业时添加新建的委托信息。委托权限示例请参考[创建自定义委托](https://support.huaweicloud.com/usermanual-aidatalake/aidatalake_01_0078.html)。 2. **LakeFormation SQL资源授权：授权使用LakeFormation具体资源。** LakeFormation资源授权是指允许用户对特定资源（元数据、数据库、表、列和函数等）的访问的权限，以此来控制对LakeFormation的数据和元数据的访问。 在LakeFormation管理控制台，对资源授权。Spark Job支持角色和委托两种主体类型。 了解LakeFormation SQL资源权限请参考[配置LakeFormation元数据权限](https://support.huaweicloud.com/usermanual-lakeformation/lakeformation_03_00014.html)。 #### SQL鉴权 ![](https://support.huaweicloud.com/usermanual-aidatalake/public_sys-resources/caution_3.0-zh-cn.png) - 除了表格内的权限，IAM侧还需要配置lakeformation:policy:describe。 - 由于Spark集群启动时默认会校验default数据库，所以在执行任何SQL前，需要在LakeFormation控制台上先为目标Catalog下的default数据库授予DESCRIBE权限，授权操作请参考[配置LakeFormation元数据权限](https://support.huaweicloud.com/usermanual-lakeformation/lakeformation_03_00014.html)。 - 建议不要给lakeformation:policy:create权限，给了会被视为管理员，跳过SQL鉴权。 - [Iceberg] 表1Iceberg鉴权 | 分类 | SQL | LakeFormation SQL资源鉴权权限 | IAM权限 | |:---|:---|:---|:---| | **DDL语句** | ALTER DATABASE | database:DESCRIBE database:ALTER | "lakeformation:database:describe", "lakeformation:database:alter" | | **DDL语句** | ALTER TABLE | database:DESCRIBE table:DESCRIBE table:ALTER database:CREATE_TABLE column:SELECT或table:SELECT | "lakeformation:database:describe", "lakeformation:table:describe", "lakeformation:table:alter", "lakeformation:table:create" | | **DDL语句** | ALTER VIEW | database:DESCRIBE database:CREATE_TABLE table:DESCRIBE table:ALTER column:SELECT | "lakeformation:database:describe", "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg ALTER COLUMN col TYPE BIGINT | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg ADD PARTITION FIELD col | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg DROP PARTITION FIELD col | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg REPLACE PARTITION FIELD col | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg WRITE writeSpec | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg SET IDENTIFIER_KW FIELDS fieldList | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg DROP IDENTIFIER_KW FIELDS fieldList | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg SET TBLPROPERTIES | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg create/Replace BRANCH Test_branch | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg create/Replace Tag Test_tag | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg DROP BRANCH Test_branch | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | ALTER TABLE Test_Iceberg DROP TAG Test_tag | table:DESCRIBE table:ALTER | "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | CREATE DATABASE | database:DESCRIBE catalog:CREATE_DATABASE | "lakeformation:database:describe", "lakeformation:database:create" | | **DDL语句** | CREATE TABLE Test_Iceberg USING iceberg | database:DESCRIBE database:CREATE_TABLE table:DESCRIBE | "lakeformation:database:describe", "lakeformation:table:describe", "lakeformation:table:create" | | **DDL语句** | CREATE VIEW | database:DESCRIBE database:CREATE_TABLE table:DESCRIBE（source\\target） table:DROP(target) column:SELECT | "lakeformation:database:describe", "lakeformation:table:describe", "lakeformation:table:create", "lakeformation:table:drop" | | **DDL语句** | CREATE TABLE Test_Iceberg AS SELECT xx From xx Where | table:DESCRIBE table:ALTER table:DROP table:INSERT database:CREATE_TABLE database:DESCRIBE column:SELECT | "lakeformation:database:describe", "lakeformation:table:describe", "lakeformation:table:create", "lakeformation:table:alter", "lakeformation:table:drop" | | **DDL语句** | DROP DATABASE | database:DESCRIBE database:DROP | "lakeformation:database:describe", "lakeformation:database:drop" | | **DDL语句** | DROP TABLE | database:DESCRIBE table:DESCRIBE table:DROP | "lakeformation:database:describe", "lakeformation:table:describe", "lakeformation:table:drop" | | **DDL语句** | DROP VIEW | database:DESCRIBE table:DESCRIBE(target\\source) table:DROP(target) | "lakeformation:database:describe", "lakeformation:table:describe", "lakeformation:table:drop" | | **DDL语句** | REPAIR TABLE | database:DESCRIBE table:DESCRIBE table:ALTER table:SELECT | "lakeformation:database:describe", "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | TRUNCATE TABLE | database:DESCRIBE table:DESCRIBE table:SELECT table:UPDATE | "lakeformation:database:describe", "lakeformation:table:describe", "lakeformation:table:alter" | | **DDL语句** | REPLACE TABLE Test_Iceberg (col1..col2..)
