------------------------------------
Summary: Produce Ranger audit events for role-related SHOW
statements
Key: IMPALA-15046
URL: https://issues.apache.org/jira/browse/IMPALA-15046
Project: IMPALA
Issue Type: Task
Reporter: Fang-Yu Rao
When Apache Ranger is the authorization provider for Apache Hive, Hive produces
Ranger audit events for the statements {{{}SHOW ROLES{}}}, {{{}SHOW ROLE GRANT
USER/GROUP{}}}, and {{{}SHOW CURRENT ROLES{}}}. It would be good if Impala
could produce Ranger audit events for those statements.
- {{SHOW ROLES}} is processed by
[RangerHiveAuthorizer#getAllRoles()|https://github.com/apache/ranger/blob/c5b55a4/hiveagent/src/main/java/org/apache/ranger/authorization/hive/authorizer/RangerHiveAuthorizer.java#L1168-L1220],
and the following is used to produce the audit event.
{code:java}
RangerAccessResult accessResult = createAuditEvent(hivePlugin,
currentUserName, userNames, HiveOperationType.SHOW_ROLES,
HiveAccessType.SELECT, null, result);
hivePlugin.evalAuditPolicies(accessResult);
auditHandler.processResult(accessResult);
auditHandler.flushAudit();
{code}
- {{SHOW ROLE GRANT USER/GROUP}} is processed by
[RangerHiveAuthorizer#getRoleGrantInfoForPrincipal()|https://github.com/apache/ranger/blob/c5b55a4/hive-agent/src/main/java/org/apache/ranger/authorization/hive/authorizer/RangerHiveAuthorizer.java#L457-L528],
and the following is used to produce the audit event.
{code:java}
RangerAccessResult accessResult = createAuditEvent(hivePlugin,
currentUserName, userNames, HiveOperationType.SHOW_ROLE_GRANT,
HiveAccessType.SELECT, principalInfo, result);
hivePlugin.evalAuditPolicies(accessResult);
auditHandler.processResult(accessResult);
auditHandler.flushAudit();
{code}
- {{SHOW CURRENT ROLES}} is processed by
[RangerHiveAuthorizer#getCurrentRoleNames()|https://github.com/apache/ranger/blob/c5b55a4/hive-agent/src/main/java/org/apache/ranger/authorization/hive/authorizer/RangerHiveAuthorizer.java#L1299-L1332],
and the following is used to produce the audit event.
{code:java}
RangerAccessResult accessResult = createAuditEvent(hivePlugin,
user, userNames, HiveOperationType.SHOW_ROLES, HiveAccessType.SELECT, ret,
result);
hivePlugin.evalAuditPolicies(accessResult);
auditHandler.processResult(accessResult);
auditHandler.flushAudit();
{code}
