> Add ability to import file ACLs from remote store

> Key: HDFS-14856
> URL: https://issues.apache.org/jira/browse/HDFS-14856
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Ashvin Agrawal
> Assignee: Ashvin Agrawal
> 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.
