Chris Douglas commented on HDFS-12970:
--------------------------------------
This is by design. {{HdfsFileStatus}} needs to be qualified before it can be
returned to the user, since the NameNode doesn't return fully qualified URIs.
Prior to HDFS-12681, it was qualified as it was copied into a {{FileStatus}}
object. Since {{HdfsFileStatus}} is now a subtype of {{FileStatus}}, the path
is initialized as null in the constructor and set later by the client.
Are you observing the path is {{null}} when it's returned to the user?
> HdfsFileStatus#getPath returning null.

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs
> Affects Versions: 3.1.0
> Reporter: Rushabh S Shah
> Priority: Critical
>
> After HDFS-12681, HdfsFileStatus#getPath() returns null.
> I don't think this is expected.
> Both the implementation of {{HdfsFileStatus}} sets the path to null.
