HBase provides the means to manage user access to Hive database tables directly from the command line. The most commonly-used commands are:
GRANT
Syntax:
grant '
<user-or-group>','
<permissions>','
<table>For example, to create a policy that grants user1 read/write permission on the table usertable, the command is
grant 'user1','RW','usertable'
The syntax is the same for granting CREATE and ADMIN rights.
REVOKE
Syntax:
revoke '
<user-or-group>','<usertable>'For example, to revoke the read/write access of user1 to the table usertable, the command is
revoke 'user1','usertable'
Note Unlike Hive, HBase has no specific revoke commands for each user privilege.
