-----------------------------------
Hi [~temple.zhou]
In my opinion, the true problem is the wrong update user logic when
authenticating.
In the past, Kylin will update the user per authentication, and after
KYLIN-3562, it has been removed, so there won't be so many
updates.(https://issues.apache.org/jira/browse/KYLIN-3562)
And I think it's reasonable to clear cache when the user has been updated.
