[jira] [Commented] (ACCUMULO-2200) Implement blocking password change

["Christopher Tubbs (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ACCUMULO-2200?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13872499#comment-13872499 ] 

Christopher Tubbs commented on ACCUMULO-2200:
---------------------------------------------

This issue affects more than just password changes. The problem is basically that there's no good (scalable) way to expire the ZooKeeper cache in one JVM after a change is made in a different JVM. For the narrow scope of this issue, we could probably have the ZKAuthenticator expire its cache on failure and retry, before actually returning an authentication failure. This strategy seems to be used elsewhere (table operations) and works reasonably well.

> We should have a blocking password change method that users can use. Our tests would benefit from this by no longer needing to use blind sleep statements, and users could be assured that the change has propogated before starting up other clients.
