  • hbase权限管理

    给用户分配对每个表的操作权限,有RWXCA五种,对应READ, WRITE, EXEC, CREATE, ADMIN

    hbase(main):222:0> help "grant"

    Grant users specific rights.

    Syntax: grant <user or @group>, <permissions> [, <table> [, <column family> [, <column qualifier>]]]

    Syntax: grant <user or @group>, <permissions>, <@namespace>

    permissions is either zero or more letters from the set "RWXCA". READ('R'), WRITE('W'), EXEC('X'), CREATE('C'), ADMIN('A')

    Note: Groups and users are granted access in the same way, but groups are prefixed with an '@'       character. Tables and namespaces are specified the same way, but namespaces are       prefixed with an '@' character.

    For example:

        hbase> grant 'bobsmith', 'RWXCA'    

    hbase> grant '@admins', 'RWXCA'   

      hbase> grant 'bobsmith', 'RWXCA', '@ns1'   

      hbase> grant 'bobsmith', 'RW', 't1', 'f1', 'col1'    

    hbase> grant 'bobsmith', 'RW', 'ns1:t1', 'f1', 'col1'


     查看权限

    hbase(main):220:0> help "user_permission"

    Show all permissions for the particular user. Syntax : user_permission <table>

    Note: A namespace must always precede with '@' character.

    For example:

        hbase> user_permission    

    hbase> user_permission '@ns1'    

    hbase> user_permission '@.*'    

    hbase> user_permission '@^[a-c].*'   

      hbase> user_permission 'table1'   

      hbase> user_permission 'namespace1:table1'    

    hbase> user_permission '.*'   

      hbase> user_permission '^[A-C].*'


      收回权限

    hbase(main):221:0> help "revoke"

    Revoke a user's access rights.

    Syntax:

    revoke <user or @group> [, <table> [, <column family> [, <column qualifier>]]]

    Syntax:

    revoke <user or @group>, <@namespace>

    Note: Groups and users access are revoked in the same way, but groups are prefixed with an '@'       character. Tables and namespaces are specified the same way, but namespaces are       prefixed with an '@' character.

    For example:

        hbase> revoke 'bobsmith'
