Colin Patrick McCabe commented on HDFS-5899:
--------------------------------------------
bq. Here is a compromise proposal. Let's reject the API calls when
dfs.namenode.acls.enabled is false, but let's still load and enforce all
existing ACLs found in fsimage or edits.
Sounds reasonable.
> Add configuration flag to disable/enable support for ACLs.

> Add a new configuration property that allows administrators to toggle support

> conservative choice, and administrators interested in using ACLs can enable
