REVOKE statement

Syntax:

      REVOKE privilege ON object_type object_name
      FROM USER user_name
      REVOKE privilege ON object_type object_name
      FROM GROUP group_name
      
        privilege ::= ALL | ALTER | CREATE | DROP | INSERT | REFRESH | SELECT | SELECT(column_name)
      
      object_type ::= SERVER | URI | DATABASE | TABLE
    

See the GRANT statement for the required privileges and the scope for SQL operations.

The ALL privilege is a distinct privilege and not a union of all other privileges.

The following syntax is supported when Impala is using Ranger to manage authorization.

REVOKE privilege ON object_type object_name
  FROM USER user_name

REVOKE privilege ON object_type object_name
  FROM GROUP group_name


  privilege ::= ALL | ALTER | CREATE | DROP | INSERT | REFRESH | SELECT | SELECT(column_name)

object_type ::= SERVER | URI | DATABASE | TABLE

You cannot revoke a privilege granted with the WITH GRANT OPTION. If a privilege is granted with the WITH GRANT OPTION, first revoke the grant option, and then revoke the privilege.

Typically, the object name is an identifier. For URIs, it is a string literal.

The ability to grant or revoke SELECT privilege on specific columns is available in Impala 2.3 and higher.

Required privileges:

Only administrative users those with ALL privileges on the server can use this statement.

Compatibility:

Cancellation: Cannot be cancelled.

HDFS permissions: This statement does not touch any HDFS files or directories, therefore no HDFS permissions are required.
