We’re excited today to announce the availability of File and Folder ACLs for the Azure Data Lake Store. Many of you have been eagerly awaiting this feature because it is critical in securing their big data.
When we launched the preview of Data Lake Store in October 2015, filesystem security was controlled by a single ACL at the root of store that applied to all files and folders underneath.
Starting today, ACLs can be set on any file or folder within the store, not just the root folder.
We’ve emphasized that Azure Data Lake Store is compatible with WebHDFS. Now that ACLs are fully available, it’s important to understand the ACL model in WebHDFS/HDFS because they are POSIX-style ACLs and not Windows-style ACLs.

Repeating manual steps is both irritating and prone to error. It’s easier if you use Active Directory security groups.
First give the needed permissions to the security group. Afterwards, adding new users is simple: just add them to the security group. This will dramatically simplify maintaining and securing your Data Lake.
