[jira] [Commented] (IMPALA-7795) Add a command to refresh authorization data

    [ https://issues.apache.org/jira/browse/IMPALA-7795?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16670501#comment-16670501 ] 

Philip Zeyliger commented on IMPALA-7795:
-----------------------------------------

Note that we expose a lot of these already (refresh, invalidate, etc.) and they're hugely confusing.

> There is currently no way to refresh authorization data (privileges and principals) without calling "invalidate metadata" (which is very costly) and increasing the polling time. There needs to be a way to explicitly refresh the authorization data similar to "refresh functions".
