Subject [jira] [Commented] (ACCUMULO-3412) Consistent application of runtime configuration changes
Date Fri, 12 Dec 2014 23:01:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3412?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14244943#comment-14244943

Josh Elser commented on ACCUMULO-3412:
--------------------------------------

bq. allow for client notification when a configuration change has been applied across the
cluster.

I would think that it simpler to update the calls which change said configuration to block
until the configuration is consistent across all (or the necessary) nodes.

> Right now changes to runtime configurable properties are lazily applied across the cluster.
Define stricter rules about when rules are in affect.
> * Minimal goal: allow for client notification when a configuration change has been applied
across the cluster.
> * Stretch: do something fancy so that we have consistent application across the cluster
(e.g. either all tablet servers are applying a constraint to a table or none are)
