> 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.
