<!-- Copied from Sentry docs. Turn into conref. -->
|
|
The <codeph>CREATE ROLE</codeph> statement creates a role to which privileges can be granted. Privileges can
|
|
be granted to roles, which can then be assigned to users. A user that has been assigned a role will only be
|
|
able to exercise the privileges of that role. Only users that have administrative privileges can create/drop
|
|
roles. By default, the <codeph>hive</codeph>, <codeph>impala</codeph> and <codeph>hue</codeph> users have
|
|
administrative privileges in Sentry.

<p conref="../shared/impala_common.xml#common/privileges_blurb"/>
|
|
|

<p>
|
|
Only administrative users (those with <codeph>ALL</codeph> privileges on the server, defined in the Sentry
|
|
policy file) can use this statement.

Impala makes use of any roles and privileges specified by the <codeph>GRANT</codeph> and
|
|
<codeph>REVOKE</codeph> statements in Hive, and Hive makes use of any roles and privileges specified by the
|
|
<codeph>GRANT</codeph> and <codeph>REVOKE</codeph> statements in Impala. The Impala <codeph>GRANT</codeph>
|
|
and <codeph>REVOKE</codeph> statements for privileges do not require the <codeph>ROLE</codeph> keyword to be
|
|
repeated before each role name, unlike the equivalent Hive statements.
