--------------------------------
Hadoop Flags: Incompatible change
> AdlFileSystem.getAclStatus() returns unexpected ACL information
> ---------------------------------------------------------------
>
> Key: HADOOP-14437
> URL: https://issues.apache.org/jira/browse/HADOOP-14437
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/adl
> Reporter: Sailesh Mukil
> Labels: acl, api-breaking
>
> 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.
