Subject [jira] [Commented] (HADOOP-13437) KMS should reload whitelist and default key ACLs when hot-reloading
Date Tue, 16 Aug 2016 00:01:38 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13437?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15421918#comment-15421918

Xiao Chen commented on HADOOP-13437:
------------------------------------

Thanks for the review and discussions, Arun and Andrew.

Personally I would prefer #2, since I think this would minimize user surprise, and make things
easier to maintain, both for developers and admins. This way, we can treat this as a bug fix,
and put it into 2.x. #1 will be incompatible so we can't do anything until 3.0. m2c.

> When hot-reloading, {{KMSACLs#setKeyACLs}} ignores whitelist and default key entries
if they're present in memory.
> We should reload them, hot-reload and cold-start should not have any difference in behavior.
> Credit to [~dilaver] for finding this.
