-------------------------------
Summary: RBF should support get the information about ancestor
mount points
Key: HDFS-16724
URL: https://issues.apache.org/jira/browse/HDFS-16724
Project: Hadoop HDFS
Issue Type: Bug
Reporter: ZanderXu
Assignee: ZanderXu
Suppose RBF cluster have 2 nameservices and to mount point as below:
* /user/ns1 -> ns1 -> /user/ns1
* /usre/ns2 -> ns2 -> /user/ns2
Suppose we disable default nameservice of the RBF cluster and try to
getFileInfo of the path /user, RBF will throw one IOException to client due to
can not find locations for path /user.
But as this case, RBF should should return one valid response to client,
because /user has two sub mount point ns1 and ns2.
