Sailesh Mukil created HADOOP-14437:
--------------------------------------
Summary: 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
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.
