--------------------------------------
dfsrouteradmin command returns mode 0755

[aajisaka@aajisaka-hadoop-r1 ~]$ hdfs dfsrouteradmin -ls
Mount Table Entries:

> RBF: Add more information to HdfsFileStatus for a mount point

> Key: HDFS-14011
> URL: https://issues.apache.org/jira/browse/HDFS-14011
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Akira Ajisaka
> Assignee: Akira Ajisaka
> Priority: Major
>
> RouterClientProtocol#getMountPointStatus does not use information of the
> mount point, therefore, 'hdfs dfs -ls' to a directory including mount point
> returns the incorrect information.
