-------------------------------
Summary: 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
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Hoss Man
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.
