Subject [jira] [Commented] (HIVE-20457) Create authorization mechanism for granting/revoking privileges to change Hive properties
Date Fri, 24 Aug 2018 15:50:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-20457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16591838#comment-16591838
] 

Thejas M Nair commented on HIVE-20457:
--------------------------------------

When either sql standard authorization or ranger authorization is enabled, it automatically
limits the configuration changes to configs in a whitelist. The config that is used for this
can also be configured using [whitelist configuration|https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.security.authorization.sqlstd.confwhitelist]

There is also [hive.conf.restricted.list|https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.conf.restricted.list]
config parameter. 

There is also another authorizer that does limited checks which includes whitelist auto-setup,
which is in the works. This one would work well with storage based authorization.

> At the moment any user in Hive can change any property of Hive. So he can set {{hive.exec.pre.hooks}}
to hook that implements dangerous code. It would be nice to create roles and assign list of
properties that particular role is able to modify. For example, {{admin}} role has permissions
to change any property, and {{hive_client}} can change only {{hive.txn.timeout}}.
