He Xiaoqiao created HDFS-11231:
----------------------------------

             Summary: federation support to linux-like mount type
                 Key: HDFS-11231
                 URL: https://issues.apache.org/jira/browse/HDFS-11231
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: federation
            Reporter: He Xiaoqiao


Based on Federation Arch, it can mount multi namespaces using mount table, currently, mount
point only support leaf node of mount tree as mount point, it is hard to one directory, especially
there are many children dir, for instance you have to mount hundreds of path /foo/ children
dir in mount table if you have mount one child of path /foo/. this issue will implement linux-like
mount type, and it may be more convenient to partition existing dir or add new dir to one
of arbitrary namespace.
