xuzq commented on HDFS-14739:
-----------------------------
I'm sorry, maybe I didn't express it clearly.
First, I add some mount table use the command like:
_./bin/hdfs dfsrouteradmin -add /mnt ns0 /mnt -owner mnt -group mnt_group -mode
755_
_./bin/hdfs dfsrouteradmin -add /mnt/test1 ns0 /mnt/test1 -owner mnt_test1
-group mnt_test1_group -mode 755_
_./bin/hdfs dfsrouteradmin -add /test1 ns1 /test1 -owner test1 -group test1
-mode 755_
Second, use hadoop fs shell to LS (in order to do getListing rpc), like:
_./bin/hadoop fs -ls /mnt_
And the result of FsShell Ls does not match my expect.
> RBF: LS command for mount point shows wrong owner and permission information.

> When do getListing("/mnt"), the owner of */mnt/test1* should be *mnt_test1*
> instead of *test1* in result.
>
> And if the mount table as blew, we should support getListing("/mnt") instead
> of throw IOException when dfs.federation.router.default.nameservice.enable is
> false.
