HDFS-14856. Fetch file ACLs while mounting external store. by ashvina · Pull Request #1478 · apache/hadoop

ashvina · 2019-09-19T17:19:08Z

Addresses https://issues.apache.org/jira/browse/HDFS-14856.
If configuration dfs.namenode.mount.acls.enabled is set (true), FsTreeWalk will fetch ACLs of files on the external storage system provided at the time of mount.

Should we refer to PROVIDED here?

Agree. WDYT about dfs.namenode.provided.acls.enabled?
Keep namenode since the config is a NN config.
Replaced mount with provided so that the config name is consistent.

Better than before for sure.
Not sure about the end policy for distinguishing namenode from not.
It should be consistent.

hadoop-tools/hadoop-fs2img/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSTreeWalk.java

Do we support adding null to the acls?
Is there a finer grain exception then IOException?

ACL can be null.
IOException comes from the FileSystems API, AclStatus getAclStatus(Path path) throws IOException

hadoop-tools/hadoop-fs2img/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSTreeWalk.java

This one we don't care about the IOE?

Good catch. The scanner will not fail if the remote FS does not support ACLs. All other IOException fail the operation in all paths now. Thanks !

@ashvina - is it possible to handle the exception the same way in both the constructors?

getUser()
Is this static?

Why do we have this just for doing a get?

The user mapping behavior can be different in a subclass. For e.g. In this case SingleUGIResolver maps all users to a single user.

hadoop-tools/hadoop-fs2img/src/main/java/org/apache/hadoop/hdfs/server/namenode/TreePath.java

So, this is not currently written to the image?

Yes. I am proposing to fix the scanner in the PR which is independent of the ImageWriter. The consumer of the scanner can choose to ignore the ACL.

Can you make this explicit (e.g,, add javadoc for this method)?

No. Static will not work as resolution methods in the subclass may not be static.
