Subject [jira] [Commented] (CURATOR-221) ACLProvider is not respected on parent nodes after calling CuratorFramework.usingNamespace
Date Mon, 18 May 2015 21:37:59 GMT

    [ https://issues.apache.org/jira/browse/CURATOR-221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14549276#comment-14549276

Mike Drob commented on CURATOR-221:
-----------------------------------

I'm not sure this is a bug in Curator. When you are operating inside of a namesapce, it does
not seem unreasonable that you can only apply ACLs to things inside of that namespace.

>             Project: Apache Curator

> See HADOOP-11973 for some background information.
> Here's a high level overview of the issue I'm seeing:
> 1) I create a CuratorFramework with a non-default ACLProvider
> 2) I call framework.usingNamespace("/solr/zkdtsm") on the curator framework
> 3) I do some action, like starting a new SharedCount on a subnode of the namespace /testPath/ZKDTSMRoot/ZKDTSMSeqNumRoot
> Result: the tree is created, but neither /solr nor /solr/zkdtsm have ACLs, while /testPath/ZKDTSMRoot/ZKDTSMSeqNumRoot
does.  I would expect all those nodes would have ACLs because I only performed zookeeper actions
on a CuratorFramework with an ACLProvider specified.
> This seems to happen because NamespaceImpl does not save the ACLProvider, see this line:

> Then, when an action is performed on the namespace, fixForNamespace is called:
> https://github.com/apache/curator/blob/7f2098654a26e2f593801a586ce68300f54abf15/curator-framework/src/main/java/org/apache/curator/framework/imps/NamespaceImpl.java#L74
> resulting in the parents being created without an ACL.
