Rushabh S Shah commented on HDFS-12970:
---------------------------------------
bq. Are you observing the path is null when it's returned to the user?
No.
My use case: While working on HDFS-12811, I was issuing
{{FSNamesystem#getFileInfo}} call from {{NamenodeFsck}} and trying to extract
path from HdfsFileStatus.
Thats where it returned null.
bq. the path is initialized as null in the constructor and set later by the
client.
If I understand your previous comment correctly, I have to cast the returned
file status to either {{HdfsNamedFileStatus}} or {{HdfsLocatedFileStatus}}
explicitly ?
> HdfsFileStatus#getPath returning null.

> Components: hdfs
> Affects Versions: 3.1.0

> After HDFS-12681, HdfsFileStatus#getPath() returns null.
> I don't think this is expected.
> Both the implementation of {{HdfsFileStatus}} sets the path to null.
