Subject [jira] [Commented] (HADOOP-13437) KMS should reload whitelist and default key ACLs when hot-reloading
Date Tue, 02 May 2017 19:17:04 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13437?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15993545#comment-15993545

Rushabh S Shah commented on HADOOP-13437:
-----------------------------------------

We recently ran into this bug in branch-2.8.
I think we should back-port this patch back to branch-2.8.
Also I think we should back-port all the bug fixes back to branch-2.8 and branch-2.7 if the
bug was introduced in 2.6.
[~xiaochen], [~andrew.wang]: Do you know of any more surprises (bug fixes) in EZ feature which
are not back-ported all the way back to branch-2.8 ?

> 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.
