ASF GitHub Bot updated HIVE-28739: ---------------------------------- Labels: pull-request-available (was: ) > support restricting users to create deferred view > ------------------------------------------------- > > Key: HIVE-28739 > URL: https://issues.apache.org/jira/browse/HIVE-28739 > Project: Hive > Issue Type: New Feature > Components: Authorization > Reporter: YUBI LEE > Assignee: YUBI LEE > Priority: Minor > Labels: pull-request-available > > In our environment, we use Impala with HiveMetastore. Since "impala" user is > a proxy user, if I create a view through Impala, it will create a view, not a > deferred view. (impala doesn't have impersonation support) > In our policy, we want to force users to create deferred view if there is no > special reason not to create deferred view in order to follow permissions of > source tables. > So I tried to exclude "impala" user from proxy user, there is some bottle > neck and the change even causes impala cluster hang. I guess that with > HiveMetastoreAuthorizer, impala cannot skip authorization if I exclude > "impala" user from proxy user. > Also, on impala side, Ranger authorization is already applied. It is > meaningless because the same hive policy applied already on impala side. > Therefore, I gave up to exclude "impala" user from proxy user. > As a result, I suggest a new configuration > "metastore.users.restricted_to_deferred_view" to support a feature that makes > some of proxyusers to be forced to create deferred view. -- This message was sent by Atlassian Jira (v8.20.10#820010)
