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.
