>            Priority: Major
> Provided storage (HDFS-9806) allows data on external storage systems to 
> seamlessly appear as files on HDFS. However, in the implementation today, the 
> external store scanner, {{FsTreeWalk,}} ignores any ACLs on the data. In a 
> secure HDFS setup where external storage system and HDFS belong to the same 
> security domain, uniform enforcement of the authorization policies may be 
> desired. This task aims to extend the ability of the external store scanner 
> to support this use case. When configured, the scanner should attempt to 
> fetch ACLs and provide it to the consumer.
