SOLR-13464: fix javadoc typo that precommit somehow missed?
> Sporadic Auth + Cloud test failures, probably due to lag in nodes reloading
> security config
> -------------------------------------------------------------------------------------------

> Key: SOLR-13464
> URL: https://issues.apache.org/jira/browse/SOLR-13464
> Project: Solr
> Issue Type: Bug
> Reporter: Hoss Man
> Priority: Major
>
> I've been investigating some sporadic and hard to reproduce test failures
> related to authentication in cloud mode, and i *think* (but have not directly
> verified) that the common cause is that after uses one of the
> {{/admin/auth...}} handlers to update some setting, there is an inherient and
> unpredictible delay (due to ZK watches) until every node in the cluster has
> had a chance to (re)load the new configuration and initialize the various
> security plugins with the new settings.
> Which means, if a test client does a POST to some node to add/change/remove
> some authn/authz settings, and then immediately hits the exact same node (or
> any other node) to test that the effects of those settings exist, there is no
> garuntee that they will have taken affect yet.
