SQL Standard-based Authorization with GRANT And REVOKE SQL Statements

SQL Standard-based Authorization with `GRANT` And `REVOKE` SQL Statements

Secure SQL standard-based authorization using the GRANT and REVOKE SQL statements is supported in Hive 0.13 and later. Hive provides three authorization models: SQL standard-based authorization, storage-based authorization, and default Hive authorization. In addition, Ranger provides centralized management of authorization for all HDP components. Use the following procedure to manually enable standard SQL authorization:

	Note
	This procedure is unnecessary if your Hive administrator installed Hive using Ambari.

Set the following configuration parameters in hive-site.xml :

Table 2.3. Configuration Parameters for Standard SQL Authorization
Configuration Parameter
Required Value
hive.server2.enable.doAs
false
hive.users.in.admin.role
Comma-separated list of users granted the administrator role.

Configuration Parameter	Required Value
`hive.server2.enable.doAs`	`false`
`hive.users.in.admin.role`	Comma-separated list of users granted the administrator role.

Start HiveServer2 with the following command-line options:

Table 2.4. HiveServer2 Command-Line Options

Command-Line Option	Required Value
`-hiveconf hive.security.authorization.manager`	`org.apache.hadoop.hive.ql.security. authorization. MetaStoreAuthzAPIAuthorizerEmbedOnly`
`-hiveconf hive.security.authorization.enabled`	`true`
`-hiveconf hive.security.authenticator.manager`	`org.apache.hadoop.hive.ql.security. SessionStateUserAuthenticator`
`-hiveconf hive.metastore.uris`	`''`(a space inside single quotation marks)

Note

Administrators must also specify a storage-based authorization manager for Hadoop clusters that also use storage-based authorization. The hive.security.authorization.manager configuration property allows multiple authorization managers in comma-delimited format, so the correct value in this case is:

hive.security.authorization.manager=org.apache.hadoop.hive.ql.security.authorization.StorageBasedAuthorizationProvider, 

org.apache.hadoop.hive.ql.security.authorization.MetaStoreAuthzAPIAuthorizerEmbedOnly
