> ----------------------------------------------------------------------------
>
> Key: DRILL-5671
> URL: https://issues.apache.org/jira/browse/DRILL-5671
> Project: Apache Drill
> Issue Type: New Feature
> Components: Server
> Reporter: Karthikeyan Manivannan
> Assignee: Karthikeyan Manivannan
> Priority: Major
> Labels: doc-impacting
> Fix For: 1.15.0
>
>
> All Drill ZK nodes, currently, are assigned a default [world:all] ACL i.e.
> anyone gets to do CDRWA(create, delete, read, write, admin access). This
> means that even on a secure cluster anyone can perform all CRDWA actions on
> the znodes.
> This should be changed such that:
> - In a non-secure cluster, Drill will continue using the current default
> [world:all] ACL
> - In a secure cluster, all nodes should have an [authid: all] ACL i.e. the
> authenticated user that created the znode gets full access. The discovery
> znodes i.e. the znodes with the list of Drillbits will have an additional
> [world:read] ACL, i.e. the list of Drillbits will be readable by anyone.
