> The HDFS getAclStatus() returns ACL information of a file and how that pertains to a
Hadoop user/group.
> However, the ADLS getAclStatus() returns ACL information of a file but does not map them
to Hadoop users/groups and instead maps them to the client ID of the SPI.
> The components built around Hadoop use this API with the expectation that the ACL information
returned will be mapped to Hadoop users/groups, i.e. the components expect it to have the
same behavior as other filesystems that support this API.
> If not, the components need to have logic to handle this case where if they're talking
to ADLS, they won't look for matching the Hadoop user/group, but instead the client ID. And
once AdlFileSystem changes its API to be able to map to Hadoop users/groups, it will be a
breaking change for all the components.
> Until such functionality is able to be provided, I would suggest that the getAclStatus()
be unsupported, just as it is in S3AFileSystem.
