wangzhiyuan updated HDFS-13233:
-------------------------------
Description:
Method MountTableResolver->getMountPoint will traverse mount table and return
the first mount point which the input path starts with, but the condition is
not sufficient.
Suppose the mount point table contains: "/user" "/user/test" "/user/test1", if
the input path is "/user/test111", the return mount point is "/user/test1", but
the correct one should be "/user".
was:Suppose the mount point table include: "/" "/user" "/user/test"
"/user/test1", if the input path is "/user/test111", the return mount point of
(MountTableResolver->getMountPoint) is "/user/test1", but the correct one
should be "/user".
> RBF：getMountPoint doesn't return the correct mount point of the mount table
