Allen Wittenauer commented on HDFS-8322:
----------------------------------------
The base assumption proposed in this JIRA is that the distributed file system
in use is HDFS. If I'm using a distributed file system such as lustre or
glustre or any number of other mountable distributed file systems, using hadoop
fs -ls using LocalFileSystem is completely normal.
So, -1 from me.
