Creating Databases and Creating Tables in the Default Database Only as the Hive Administrator¶
Scenario¶
This function is applicable to Hive and Spark2x.
After this function is enabled, only the Hive administrator can create databases and tables in the default database. Other users can use the databases only after being authorized by the Hive administrator.
Note
After this function is enabled, common users are not allowed to create a database or create a table in the default database. Based on the actual application scenario, determine whether to enable this function.
Permissions of common users are restricted. In the scenario where common users have been used to perform operations, such as database creation, table script migration, and metadata recreation in an earlier version of database, the users can perform such operations on the database in the condition that this function is disabled temporarily after the database is migrated or after the cluster is upgraded.
Procedure¶
Log in to FusionInsight Manager. For details, see Accessing FusionInsight Manager. Choose Cluster > Services > Hive > Configurations > All Configurations.
Choose HiveServer(Role) > Customization, add a customized parameter to the hive-site.xml parameter file, set Name to hive.allow.only.admin.create, and set Value to true. Restart all Hive instances after the modification.
Determine whether to enable this function on the Spark2x client.
If yes, download and install the Spark2x client again.
If no, no further action is required.
